Reintroduce keymaps build and test

This commit reintroduces code to

 1) build src/keymap
 2) test keymap/Makefile.am that it has all the key maps listed
 3) test that all the key names in keymap/* are in <linux/input.h>
 4) do a syntax check on rules/*.rules which now includes
    95-keymap.rules and 95-keyboard-force-release.rules

For #4, the regex expressions in rule-syntax-check.py had to be
updated.  They do not allow trailing comments via # comment, and
I did not include that.  A rule in 95-keymap.rules had to have its
comment moved from the end to another line.
