The rexglue codegen tool segfaults/aborts during static teardown AFTER
writing its output (cvar registry SIOF + heap corruption at exit). The
generated source is complete and valid, so generate-skate3/generate-eawebkit
now wrap the invocation with bash -c that verifies the written output files
instead of the exit code - a genuine failure (unresolved calls without the
Title Update package) produces no output and is still caught. Fixes the
release build on toolchains that hit the teardown bug (also applies to CI).
release.sh: glob the actual rexglue runtime lib name (librexruntimerd.so for
relwithdebinfo vs librexruntime.so for release) so packaging ships the lib
the binary links.
