Subject: [PATCH] v2v: linux: improve regex for resume= entries (RHBZ#1651987)

Add few more characters for the devices of resume= entries in the
command line of grub: this way it is possible to match also /dev/mapper
devices.

This should require no further processing, since the names of the
/dev/mapper devices do not change after the conversion.

(cherry picked from commit 50b08fd84bc035ada9e7a3cdda6c36ab7e418e8c)
