The availability of the compgen builtin depends on whether bash was
compiled with --enable-readline. As such, it is sensible to avoid it in
scripts intended for non-interactive shells.
Though it would have been straightforward to mimic the behaviour of
compgen -c, let's just search ${BROOT}/usr/bin instead. From what I can
gather, both dev-lang/zig and dev-lang/zig-bin install a (versioned)
symlink to /usr/bin, with there being no apparent need to search
elsewhere.
While at it, address an error of logic whereby ZIG_VER was defined as
the value of ver, rather than selected_ver.
