[PATCH 10/19] conftest.py: Add more valgrind filter patterns

[Bernd Schubert <bernd@bsbernd.com>]

From: Bernd Schubert <bschubert@ddn.com>

Valgrind complains that it does not know the fsmount syscall,
pytest checks for warnings, find that and fails the test

--14936-- WARNING: unhandled amd64-linux syscall: 430
--14936-- You may be able to write your own handler.
--14936-- Read the file README_MISSING_SYSCALL_OR_IOCTL.
--14936-- Nevertheless we consider this a bug.  Please report
--14936-- it at http://valgrind.org/support/bug_reports.html.
fuse: fsopen(fuse) failed: Function not implemented
=========================== short test summary info

Obviously we want to filter our valgrind warnings.
