PEP8: fix variours errors

pep8 1.4.6 gives the following error
tests/hooksTests.py:140:23: E127 continuation line over-indented for
visual indent
tests/hooksTests.py:141:18: E124 closing bracket does not match visual
indentation

And pep8 1.4.5 on RHEL6 gives the following error
vdsm/guestIF.py:30:5: E122 continuation line missing indentation or
outdented

This patch fixes the errors while makes pep8 1.4.5 and 1.4.6 both agree
with the fix.
