Add `skip_on_jobname` to test.json

Plan to replace the hard-coded list of 'may be skipped' framework tests in
skippable() with annotations in test.json which record 'will be skipped
in these specific CI jobs'.

If the value of the MESON_CI_JOBNAME env var (an arbitrary string
expected to be unique for each CI configuration) contains any of the
strings in the `skip_on_jobname` key in test.json, the test is expected
to output MESON_SKIP_TEST.

Unexpected skips or runs are treated as an error.

Future work: Maybe we should add additional count categories 'unexpected
skip' and 'unexpected not skipped', rather than counting those as 'skipped'
and 'failed', respectively.
