Passthrough options starting with "x-" to mtab (#894)
This implements #651, tested with bindfs.
"x-*" options are comments meant to be interpreted by userspace.
#651 is about some 3rd party mount options like 'x-gvfs-notrash'.
This also removes the test if /etc/mtab is a symlink.
This test was added in commit 5f28cd15ab43c741f6d116be4d3a9aa5d82ab385
and the corresponding ChangeLog entry in this commit points to mount
issues for read-only mtab.
However, in all recent Linux distributions /etc/mtab is a symlink to
/proc/self/mounts and never writable. In fact, util-linux 2.39
(libmount) entirely removed support for a writable mtab.
At least since util-linux 2.19 (10-Feb-2011) /run/mount/utab is used
as replacement for userspace mount entries..
