environment: Restore action for SIGPIPE.

Browse source 
Code in `ui.scm' in `initialize-guix' procedure changes the handling of
SIGPIPE to SIG_IGN.  So restore the handling to SIG_DFL so that process
executed will have the usual action.  Technically we should record what the
handling was, and restore it to the previous value, but that would be much
more invasive change.

Always setting it to SIG_DFL is at least less surprising than always setting
to SIG_IGN.

* guix/scripts/environment.scm (launch-environment): Restore default action
for SIGPIPE.
