generic/{279, 28[1-3]}: hide SIGBUS reporting from golden output
These four tests check that mmap'd cow writes fail when the
filesystem goes down. For regular filesystems the msync reports
EIO, but if quotas are enabled on xfs the write itself terminates
xfs_io with a SIGBUS. We don't care how the write fails, so don't
let the SIGBUS report escape to the golden output.
