dgit: Set $SIG{INT} to DEFAULT

There is a bug in libdpkg-perl, where Dpkg::Source::Package installs a
handler on loading.  This has the effect of making in-process C
calls (eg to libcurl) uninterruptible by ^C.

Work around it by unconditionally resetting SIGINT.  (Anyone who
deliberately invoked us with SIGINT ignored deserves to keep all the
resulting pieces.)

See #932841.
