[ng] rename: verbatim makefile fragments: *.am -> *.mk

Makes clear and manifest the fact that they are not parsed like the
other '*.am' files are (for variable and rule definitions, processing
of Automake conditionals, etc.), rather included almost verbatim (the
"almost" being the stripping of '##'-comments).

* automake.in (verbatim): Expect a suffix of '.mk', not '.am'.
* lib/am/texibuild.am: Rename ...
* lib/am/texibuild.mk: ... like this.
* lib/am/clean.am: Rename ...
* lib/am/clean.mk: ... like this.
* lib/am/check-typos.am: Rename ...
* lib/am/check-typos.mk: ... like this.
* lib/am/color-tests.am: Rename ...
* lib/am/color-tests.mk: ... like this.
* lib/am/parallel-tests.am: Rename ...
* lib/am/parallel-tests.mk: ... like this.
* lib/am/serial-tests.am: Rename ...
* lib/am/serial-tests.mk: ... like this.
* lib/am/header-vars.am: Rename ...
* lib/am/header-vars.mk: ... like this.
* lib/am/am-dir.am: Rename ...
* lib/am/am-dir.mk: ... like this.
* lib/am/common-targets.am: Rename ...
* lib/am/common-targets.mk: ... like this.
* Makefile.am (dist_am_DATA): Adjust.
* t/am-xargs-map.sh: Likewise.
* t/ensure-dir-exists.sh: Likewise.
* t/internals.tap: Likewise.
* t/memoize.tap: Likewise.
* t/verbatim.sh: Likewise.
