Don't shadow standard headers

@italic on the AUR stated that bfs from the AUR fails to build on
Manjaro.  From the build log, it seems like <time.h> doesn't get
included properly.  I assume it's picking up ./time.h instead.

I couldn't reproduce the build issue in the default configuration, but
it does fail with EXTRA_CFLAGS="-I." which isn't good.  So rename
everything with an x prefix to stop clashing.
