LU-13107 utils: remove lctl lov_getconfig command

The "lctl lov_getconfig" command has been obsolete for some time,
but was kept around for sanity test_44a to work properly.  Now
that LU-11656 has landed, "lfs getstripe -d $DIR" can be used to
get the actual layout used for files created in a directory.

Remove the lov_getconfig command along with the IOC definition
it was using.
