[LTP] [PATCH v6 0/4] Rewrite fw_load test using new API

[Andrea Cervesato <andrea.cervesato@suse.de>]

Support immutable distribution by splitting test in two:

- fw_load01 triggers request_firmware on /lib/firmware (read-only on
  immutable distributions) and it doesn't support read-only filesystems
- fw_load02 triggers request_firmware on custom path (always supported
  by any distribution)
