build: convert nested children + rewire parent recursion to native

Convert the last nested children to Makefile.in and switch their parents
from the -f fallback to native recursion (they now have generated build
Makefiles).  Rename and rewire are one unit: a pure rename would break the
parent's -f path to the (now-.in) child.

Converted (5): scmos/cif_template, doc/man, doc/tutcells, doc/html,
doc/latexfiles.  Pure renames -- still build via the srcdir derivation;
@srcdir@ substitution follows.

Rewired to native `make -C <child>` (config.status now creates the child
build dirs + Makefiles):
* scmos/Makefile.in: cif_template build + clean.
* doc/Makefile.in: install/install-tcl over man/tutcells/html/latexfiles.
* Makefile.in: the docs: target -> `make -k -C doc/latexfiles all`.
The `mkdir -p` and `-f ${MAGICSRC}/.../Makefile` are dropped in each.

* configure.in: AC_CONFIG_FILES for the 5 children; regenerated configure.
* .gitignore: ignore each generated child Makefile, same commit.

Verified out-of-tree: full `make && make install` rc=0, 376 files --
scmos recurses natively into cif_template (8 objs), docs regenerate via
native doc/latexfiles (27/28), man pages install via native doc/man.
