[Buildroot] [git commit branch/2017.02.x] bcusdk: eibd: drop local clock_gettime in USB backends

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=290b6cfdf688afd14e0c2597d9b6bd23dc67fc87
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2017.02.x

clock_gettime is defined locally, and calls pth_int_time, which
in turn calls clock_gettime.
The USB backend shouldn't overrule clock_gettime in the first place.
This patch fixes this endless recursion by removing the local defition.
