[PATCH] selftests/networking: remove timestamping clean target

[Anders Roxell]

Commit cda261f421ba ("selftests: add txtimestamp kselftest") introduced
a warning:

Makefile:14: warning: overriding recipe for target 'clean'
../../lib.mk:137: warning: ignoring old recipe for target 'clean'

Theres no need for timestamping to have its own 'clean' target. The
lib.mk file's 'clean' target gets included to the timestamping Makefile
and that should be enough.

Fixes: cda261f421ba ("selftests: add txtimestamp kselftest")
