internal/fakecgo: use libthr.so.3 instead of libpthread.so on FreeBSD (#481)
FreeBSD 15 removed the libpthread.so compatibility symlink to libthr.so from base. This caused Go binaries built with CGO_ENABLED=0 using purego's FreeBSD fakecgo path to have an unresolvable NEEDED entry for libpthread.so. libthr.so.3 is FreeBSD's actual threading implementation and has been present since at least FreeBSD 12.x. Updated gen.go and regenerated zsymbols_freebsd.go accordingly. Tested on FreeBSD 15.1-STABLE amd64: examples/libc builds and runs correctly with CGO_ENABLED=0, and readelf confirms the binary now links against libthr.so.3 instead of libpthread.so. Closes #480
