[PULL 05/13] iotests/277: use dot slash for nbd-fault-injector.py running

[Eric Blake <eblake@redhat.com>]

From: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>

If you run './check 277', check includes common.config which adjusts
$PATH to include '.' first, and therefore finds nbd-fault-injector.py
on PATH.  But if you run './277' directly, there is nothing to adjust
PATH, and if '.' is not already on your PATH by other means, the test
fails because the executable is not found.  Adjust how we invoke the
helper executable to avoid needing a PATH search in the first place.
