[PATCH for-5.2] iotests: Replace deprecated ConfigParser.readfp()

[PATCH for-5.2] iotests: Replace deprecated ConfigParser.readfp()

[Kevin Wolf]

iotest 277 fails on Fedora 33 (Python 3.9) because a deprecation warning
changes the output:

    nbd-fault-injector.py:230: DeprecationWarning: This method will be
    removed in future versions.  Use 'parser.read_file()' instead.

In fact, readfp() has already been deprecated in Python 3.2 and the
replacement has existed since the same version, so we can now
unconditionally switch to read_file().

I'm happy to queue this through my NBD tree for -rc2.

If you don't have other patches to send, I can take it through my own
tree, but if you send a pull request anyway, that's fine, too.

I've got at least one other NBD patch, and am double-checking my trees
and flagged inbox messages to see if there are any other last-minute
-rc2 candidates, so I will be sending a Pull Request on Monday.
