[PATCH] locks: export device name

From: Davidlohr Bueso <dave@gnu.org>

The lslk(8) program has not been maintained for over a decade and has recently been rewritten as lslocks(8).
It will be available for the next 2.22 release, in a couple of months. This is a good opportunity to delete
that nasty WE_CAN_BREAK_LSLK_NOW and start exporting the device name instead of the maj:min numbers.

For backward compatibility the new version can be in charge of checking older kernel versions and parsing the old
output if necessary.

Signed-off-by: Davidlohr Bueso <dave@gnu.org>
