[OE-core] [PATCH 14/17] python-pycairo: fix buildpath QA issue

[Hongxu Jia]

- Inherit waf.bbclass, remove duplicate tasks

- Get "--destdir" directory supplied to the "install" command,
  and use it as a prefix to strip off the purported filename
  encoded in bytecode files.

- Do not need to generate pycairo.pc manually
