syntax-check: Sync with gnulib

Browse Source 
The most notable change is the new 'sc_unportable_grep_q' rule.

While importing it from gnulib, the rule has been tweaked
slightly by adding superflous quotes so that syntax-check.mk
itself doesn't trip it. This is similar to the tricks employed
for the 'sc_prohibit_close' and 'sc_copyright_usage' rules,
among many others.
