Do not limit filesize when running a maintenance script

Starting HHVM may require writing very large files, so it can't have the
same file size limit as image scaling etc. The memory limit was already
disabled for much the same reason.

This is the only caller of wfShellWikiCmd() in core which proceeds to
call wfShellExec().
