common-main: call restore_sigpipe_to_default()
This is another safety/sanity setup that should be in force everywhere, but which we only applied in git.c. This did catch most cases, since even external commands are typically run via "git ..." (and the restoration applies to sub-processes, too). But there were cases we missed, such as somebody calling git-upload-pack directly via ssh, or scripts which use dashed external commands directly.
