Philip Withnall 8efe28c570 ci: Add lcov configuration to ignore g_return_*if_fail()/g_assert*()
While we can’t add markers to the macro implementations to cause lcov to
ignore them automatically, we can change our lcov configuration to
ignore all calls to them.

See https://github.com/linux-test-project/lcov/issues/44.

This causes all the un-takeable branches and un-reachable assertions to
be ignored by our code coverage, which bumps our statistics:
 • Lines: 74.9% → 74.8%
 • Functions: 82.3% → 82.3%
 • Branches: 53.3% → 64.2%

The rationale is that nobody should be testing programmer error
handling, as g_return_*if_fail() are used to guard against — so it’s not
reasonable to count missed branches like that in code coverage
statistics.
