Ensure write failure reports no-disk-space
A few places calling fwrite and gzwrite were not setting errno to ENOSPC
when reporting errors, as is customary; this led to some failures being
reported as
"could not write file: Success"
which makes us look silly. Make a few of these places in pg_dump and
pg_basebackup use our customary pattern.
