Changes

add new python package py3c

Changed package component location from:
components/python/py3c to components/library
because package does not really provide any
usefull python code, just system header files.

Replaced prep.mk, ips.mk and setup.mk with common.mk,
therefore removed the build/install targets, as requested
by AndWac.

Added TEST_TARGET= $(NO_TESTS) and changed fmri in pkg5.

Moved TEST_TARGET= $(NO_TESTS) before include $(WS_MAKE_RULES)/common.mk
