libmount: don't use /{proc,ext}/filesystems when more fs types specified
# mkfs.ext4 /dev/sda1
# mount -t foo,bar /dev/sda1 /mnt
successfully mount the device, this is unexpected as extN is no
between wanted (by -t specified) filesystems.
Summary about -t:
* "mount -t foo" mount(2) with "foo" type
* "mount -t foo,bar" try mount(2) with "foo" or "bar"
* "mount -t foo,auto" try mount(2) with "foo" or ask libblkid for
the type
* "mount -t nofoo,bar" try types from /{etc,proc}/filesystems, but
exclude "foo" and "bar"
Note that more filesystems may be specified in fstab (as comma
delimited list). The stuff from fstab is always interpreted as list
and never as a pattern ("no" prefix makes no sense in fstab).
