[ptxdist] [PATCH] tcpreplay: fix license and pin down more license files

[Bastian Krause <bst@pengutronix.de>]

As tcpreplay is GPL software, include a file mentioning that it's under
GPL (src/tcpreplay.c)

Additionally, docs/LICENSE states:

  Please note that this license covers the files that I have written.
  Some files distributed with the Tcpreplay Suite are copyrighted by
  other authors and have a different license. These files & directories
  are marked as such.

This probably applies to src/common/err.c (BSD-4-Clause-UC) and to
src/common/fakepoll.c (BSD-3-Clause).

Add those licenses and pin the corresponding files.

Originally sent as "[PATCH v2] tcpreplay: new package"
(<20240923132020.1626850-1-bst@pengutronix.de>), but v1 was already
applied on master. So turn this into a separate commit instead.

Since the above version, I've also pinned down src/tcpreplay.c.
