LU-15095 tests: skip lbug_on_grant_miscount on client

Do not try to specify the lbug_on_grant_miscount=1 module parameter
on client-only builds (el7.9, pcc64le, aarch64) as this is a server
parameter and will not be present if the client is built without
HAVE_SERVER_SUPPORT.  Otherwise, loading ptlrpc.ko will fail.
