Build fails with:
../playerctl/playerctl-player.c:274:19: error: use of undeclared identifier 'CLOCK_MONOTONIC'
    clock_gettime(CLOCK_MONOTONIC, &player->priv->cached_position_monotonic);

This flag causes the shairport-sync server to attempt to daemonize, but it looks like systemd is already handling that. With the `-d` argument, shairport-sync immediately exits—it seems that something (systemd I'm guessing?) is sending it SIGINT or SIGTERM.

The [upstream systemd unit](https://github.com/mikebrady/shairport-sync/blob/master/scripts/shairport-sync.service.in#L10) doesn't pass `-d`.

soapysdr: fix extraPackages support

shairport-sync: don't daemonize

See: opencv/opencv#13232

This also fixes the test of haskell-opencv HEAD where we got the
following error:

    Feature Detection
      houghLinesP:
libgomp: Out of memory allocating 927712937064 bytes
Test suite test-opencv: FAIL

This is the same fix as for opencv3 in commit:
2572dd11accf701feeefd6fd4ee45be98cb47016

This means `runc` becomes a multi-output derivation : `runc.bin` and `runc.man`.
