xfsprogs: fix the -V option for various shell scripts

For most of the shellscripts wrapping xfs_db or xfs_growfs the -V option
is not implemented correctly.  If we just add -V to the options for the
underlying binaries we will never actually call it because the mandatory
device / mount point argument is missing.  Instead just call the underlying
command with -V directly and exit early.  This is what xfs_bmap.sh,
xfs_mkfile and xfs_metadump.sh are already doing.
