[Buildroot] [PATCH] package/blktrace: do not build in parallel

[Yann E. MORIN]

The Makefile is not parallel safe.

Fixes numerous build failures:
    http://autobuild.buildroot.org/results/c7f/c7f0b22c6d256c75ade223af702c5f29c6c677d8/
    http://autobuild.buildroot.org/results/4ab/4abb0d2590528c634766103ee8ffd648ad5c04d3/
    ...

Look for the message:
    btreplay.o: file not recognized: File truncated
