mkdumprd: remove useless "x-initrd.mount" 

After the following systemd commit, "x-initrd.mount"
option became useless actually, we can safely remove
it now.

    fstab-generator: remove bogus condition

    The sysroot mount is already taken care of by the
    add_sysroot_mount function. With this condition
    left in, we can we can get something like this:

    initrd-root-fs.target.requires
    `-- usr.mount -> /run/systemd/generator/usr.mount

    in the main system (i.e., not in the initramfs). In
    the initramfs, the previous condition already kicks in.

[snip]

"mount_in_initrd(me)" is true with "x-initrd.mount" option,
the behaviour of systemd fstab generator changed after the
above-mentioned patch, it always generates local mount units
required by local-fs.target regardless of "x-initrd.mount".

After failure, it enters dracut emergency, further triggers
kdump emergency service, thus there is no problem.
