[ptxdist] [RFC 1/2] ptxdist: print a note when calling ptxdist inside 'ptxdist bash'

[Roland Hieber <rhi@pengutronix.de>]

For debugging purposes it might be useful to run ptxdist inside a
'ptxdist bash' session, but under normal conditions this will not work
out of the box. Mention the fact to prevent confusion and useless
debugging sessions:

    $ ptxdist
    FATAL didn't find /scripts/ptxdist_vars.sh
    Note: PTXdist was called inside 'ptxdist bash' – things may be broken.
