pidstats: Introduce process_flags method

Usage example:

>>> import procfs
>>> ps = procfs.pidstats()
>>> for t in ps.find_by_name("sirq-net-tx/6"):
...     print "%s: %s" % (t, ps.process_flags(t))
...
85: ['PF_FORKNOEXEC', 'PF_NOFREEZE', 'PF_SUPERPRIV', 'PF_THREAD_BOUND']
>>> for t in ps.find_by_name("pdflush"):
...     print "%s: %s" % (t, ps.process_flags(t))
...
398: ['PF_FLUSHER', 'PF_FORKNOEXEC', 'PF_SWAPWRITE']
399: ['PF_FLUSHER', 'PF_FORKNOEXEC', 'PF_SWAPWRITE']
>>>
