maintainer-makefile: relax coverage requirements

Adjust so that `make coverage` completes for coreutils.
There is no coverage for lib/parse-datetime.y
but everything else is fine.

* top/maint.mk (COVERAGE_CCOPTS): Since we're overriding CFLAGS,
add -Wno-error to relax warning requirements.  Projects usually default
to -O2, and changing from that can very well induce new warnings.
(build-coverage, gen-coverage): Keep going on non-fatal errors.
