[Buildroot] [git commit] swupdate: don't link with librt

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=87f8ff6d2d376fcd7f2a15346d1901f93addf9f1
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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