gfs2_edit: Fix savemeta compression for older zlibs
gzdopen in zlib 1.2.3 parses the mode string in a different way to
subsequent versions and the mode string we use causes the older gzwrite
to fail with EBADF. This patch fixes the mode string so that the
gzwrites succeed with the old and new zlibs.
