srp_unit_test had been silently skipping in test-ubuntu because the
runner image (libplacebo-ubuntu-jammy) ships without libcmocka-dev
and does not give the CI user write access to /var/lib/apt/lists, so
an in-script apt-get install cannot fix it. The silent skip is how
the SRP fixture drift reported in #215 reached a release tag.
Switch the meson detection from cc.find_library('cmocka', required:
false) to dependency('cmocka', required: false, fallback:
['cmocka', 'cmocka_dep']) and add subprojects/cmocka.wrap pointing
at WrapDB cmocka_1.1.8-1. When the runner image has cmocka the
system copy is used; otherwise meson builds it as a subproject.
Existing .gitignore rules (/subprojects/* with !*.wrap) keep the
fetched source out of the tree.
srp_unit's link line now picks up bcrypt on Windows because
random.c calls BCryptGenRandom; the main librist target was already
pulling it in via the top-level deps list, but srp_unit links
random.c directly.
Drop the broken apt-get line from the test-ubuntu script and add
retry: 2 to both test jobs to absorb the simple+multicast environmental
flake that surfaces on the shared runner regardless of branch.
