Subject: [PATCH] crystal.buildCrystalPackage: fix installCheckPhase glob
 pattern

The installCheckPhase uses `[ $f == $out/bin/*.dwarf ]` to skip .dwarf
files, but when no .dwarf files exist, the glob doesn't expand and bash's
`[` builtin fails with "unary operator expected".

Switch to `[[ ]]` which handles glob patterns correctly without expansion.
