Fully qualify libcap name in official toolchain script (#5724)

Avoid a naming collision between `libcap` and `libcap-ng` when using the `find` command to select a delta rpm in `build_official_toolchain_rpms.sh`. A proper fix should follow to always use the fully qualified path by setting a default value for `$2`  that copies `$1` in the chroot function calls.
