[PATCH blktests v2 1/2] common/rc: support multiple arguments for _require_test_dev_sysfs()

[John Pittman <jpittman@redhat.com>]

In some cases we may need to check multiple sysfs values for tests.
If this happens, create the ability to pass in multiple arguments to
_require_test_dev_sysfs() instead of having to call the function
multiple times.
