Allow GPT+EFI vdevs for root pools

Browse Source 
Commit 57a4edd allows the bootfs property to be set on any pool.
However, many of the zpool commands still prevent you from using
EFI labeled devices for the root pool.  For example:

    # zpool attach rpool /dev/sda /dev/sdb
    cannot label 'sdb': EFI labeled devices are not supported on
    root pools. on root devices.

For non-Solaris builds such as Linux disable this error.
