Link joltc with -rdynamic so build can spill its boots on Linux

Browse source 
The self-contained build reads the bundled Chez petite/scheme boots from the
joltc binary via foreign-entry on the embedded jolt_* symbols. On Linux dlsym
can't see an executable's symbols unless they're in the dynamic symbol table, so
'build' died with 'foreign-entry: no entry for jolt_petite_boot_len'. -rdynamic
exports them (macOS already resolves them). The new release self-contained-build
smoke caught this on the Linux runner.
