common/chroot-style/uchroot.sh: check if xbps-uchroot is executable
https://github.com/void-linux/void-packages/pull/48810

Description:
...and show a friendly error message

This can be a common failure mode when using `-t` if not in the group `xbps-uchroot` is owned by, because it is SUID. Previously, the error was the cryptic message `ERROR: prctl SECBIT_NOROOT (Operation not permitted)`.
