libc-test/semver/solarish.txt lists API shared by illumos and Solaris,
but do_semver only reads files named after the target family, vendor,
OS, arch and env. Neither illumos (x86_64-unknown-illumos) nor Solaris
(x86_64-pc-solaris, sparcv9-sun-solaris) has solarish as any of
those, so the list was never checked.

Read solarish.txt for both OSes. The semver test imports every list
into one module, so entries that appear twice are an error; drop the two
entries that are already in unix.txt (IP_TTL, bind) and the
exec*/fork/system entries that illumos.txt duplicates from
solarish.txt.

Testing

• cargo check for x86_64-unknown-illumos, aarch64-unknown-illumos,
  x86_64-pc-solaris and sparcv9-sun-solaris (with -Dwarnings).
• Every name in the applicable libc-test/semver lists compiles for
  illumos and Solaris; new constant values were cross-checked
  mechanically against the illumos-gate headers.
• ci/style.py checks (rustfmt, sorted/unique semver lists, style test).
• CC=clang cargo test -p libc-test on OmniOS r151060 (x86_64): passes
