trace-cmd: fix recompile error

Fixed:
make: *** No rule to make target `/path/to/sysroot/4.9.0/include/stddef.h', needed by `parse-events.o'.  Stop.
make: *** Waiting for unfinished jobs....
ERROR: oe_runmake failed

This happens when upgrade gcc from 4.9.0 to 4.9.1, and the
.parse-events.d isn't regenerated when recompile, the content of it are:

[snip]
parse-events.o: /path/to/sysroot/4.9.0/include/stddef.h
[snip]

And Makefile includes the .parse-events.d file if it exists, so there
would be errors when /path/to/sysroot/4.9.0/include/stddef.h doesn't
exist.

Remove .*.d (a few .d files, its Makefile uses this wildcard) will fix
the problem.
