Switch the 21 standard modules from the defs.mak srcdir derivation to
configure-provided substitution (same template as tiles):
srcdir = @srcdir@
VPATH = @srcdir@
MAGICDIR = @top_builddir@
defs.mak's dual-mode guard sees `srcdir` already set (origin=file) and
skips the srcdir derivation for these modules.
Verified out-of-tree: config.status writes srcdir=<src>/<mod> into each
build/<mod>/Makefile; `make modules libs` builds all 33 module libraries
(lib*.o + lib*.a, rc=0).

Second batch of the Makefile.in migration: the remaining standard modules
bplane calma cif cmwind dbwind debug drc extflat extract garouter gcr
grouter irouter mzrouter netmenu plow resis select sim textio wiring
Pure renames -- content unchanged, so each still builds via the defs.mak
srcdir derivation (dual mode); the @srcdir@ substitution follows.
* git mv <dir>/Makefile -> <dir>/Makefile.in (21 modules)
* configure.in: AC_CONFIG_FILES for each; regenerated configure. Their
build subdirs + Makefiles are now created by config.status, so
$(submake) recurses natively (make -C <dir>), no -f.
* .gitignore: ignore each generated <dir>/Makefile, in this same commit.
Verified out-of-tree: config.status writes 22 module Makefiles (these 21 +
tiles); `make modules` builds all 33 module libraries (rc=0).
