libv4l: don't link with librt 

Buildroot no longer supports toolchains with glibc older than 2.17, so there
is no need to link with librt for clock_* system calls.

The following patches are not renumbered. The noise is too high.

Subject: [PATCH] utils/qv4l2/Makefile.am: link with librt
qv4l2 uses clock_gettime(), so it should link with librt to be
compatible with old versions of glibc.
