nixos/jenkins: ensure postStart follows redirects

bjornfor · bjornfor · commit 5de8f99f0389 · 2018-03-02T08:48:38.000+01:00
Pass the -L flag to curl to make it follow redirects. This fixes an
issue I found when setting up reverse proxy for Jenkins. Without this
fix, the returned HTTP code was stuck at 302, making postStart fail the
service (it expects 200 or 403).
