build: out-of-tree outlier Makefiles — full make + install

Fix the remaining non-standard Makefiles so a full out-of-tree
`../configure && make && make install` builds and installs a complete
magic TCL tree, sources read from the source tree, all outputs in the
build tree.

Shared linker/preprocessor paths (scripts/configure.in, regenerated
scripts/configure):
* --version-script=${MAGICDIR}/magic/symbol.map -> ${MAGICSRC}/... so
  every shared-library link (tclmagic.so, ...) finds the source map.
* MCPP preproc.py path ${MAGICDIR}/scripts -> ${MAGICSRC}/scripts.

Programs (built via tcllibrary, PROGRAMS = magic tcltk):
* magic/Makefile: proto.magicrc, magicWasm.o and the bitmaps/.initrc/
  magicps.pro install copies use $< / $(srcdir) instead of bare names.
* tcltk/Makefile: magicexec/magicdnull compile $<; the sed'd launcher
  scripts (magic.tcl/.sh, ext2spice.sh, ext2sim.sh) read $<; VERSION dep
  -> ${MAGICSRC}; install-tcl copies each TCL file from the build dir if
  present else $(srcdir) (magic.tcl is generated, the rest are source).

Techs (scmos):
* scmos/Makefile: SC_PP template include -> $(srcdir)/extract_template;
  tech-file inputs (scmos.tech.in, *.tech.in) via $(srcdir)/$< ; recurse
  into cif_template with mkdir + -f ${MAGICSRC}/scmos/cif_template/Makefile;
  install copies from build-or-$(srcdir).
* scmos/cif_template/Makefile: MKDIR -> ${MAGICSRC}/scripts/mkdirs;
  SC_CPP gains -I$(srcdir); cpp reads $(srcdir)/cif{in,out}.c so the .gen
  includes resolve; objs/ generated in the build tree.

Data-file installs (source files copied from $(srcdir)):
* graphics/Makefile: glyphs, outline fonts, and the X11 helper build.
* windows/Makefile: glyphs and vector fonts.
* doc/Makefile: recurse into man/tutcells/html/latexfiles build-aware;
  doc/man, doc/tutcells install with $< ; doc/html tars $(srcdir);
  doc/latexfiles reads pre-built PostScript from ${MAGICSRC}/doc/psfiles.

Verified out-of-tree (mkdir _build; cd _build; ../configure): `make`
returns rc=0 (33 module libs, tclmagic.so, magicexec/magicdnull, scmos
tech files + cif_template objs, proto.magicrc), and
`make install DESTDIR=...` returns rc=0 installing 376 files
(bin/magic, tcl/tclmagic.so, sys/ glyphs+fonts+techs+dstyles), with the
source tree left completely clean.

Not exercised by the default TCL build/install and therefore not
converted here: the standalone .so/program variants of
lef/plot/router/ext2spice/ext2sim (their module libs do build), the
disabled oa module (-I. -> -I$(srcdir) still needed if enabled), the
WASM path, and doc/latexfiles PostScript *regeneration* (which still
writes into the source psfiles dir).
