filter: xfs_io output has dropped "64" from error messages

Upstream xfs_io has been converted to always use LFS compliant
(i.e. 64 bit) pwrite() rather than pwrite64(). Similar changes have
been made for multiple syscalls that have "*64" variants. hence the
error output of all these commands has changed, such as "pwrite64:
..." to "pwrite: ....".

Make a filter to catch the *64 variants and strip it, and
convert all the golden output to use the non-*64 variant. This will
make all golden output matching work correctly regardless of what
version of xfs_io is in use.
