qa/1286: _notrun if the Python bcc module is too old

From the comment added in this commit ...

    The netproc BCC module uses the lookup_or_try_init() method that was
    introduced in bcc v0.12.0 (released 11 Dec 2019), so determine the
    bcc version and _notrun as appropriate.

    Like most things in Pythonland, it would appear there are many (more
    that 6 according to google) ways to determine the version of a module,
    but none of them are guaranteed to work!  The recipe below seems robust
    for the bcc module.
