[LTP] [RFC] Reduce LICENCE/COPYING files

[Petr Vorel]

Hi,

We have various files which states GPL v2. I guess the reason is that LTP merged
various other smaller testsuites in the past.

$ git grep -l "GNU GENERAL PUBLIC LICENSE"  | xargs sha1sum  | sort -u

The diff is mostly different FSF address.
COPYING has been updated in 945f9c69a, others are older; not sure if it's
lastest GPL v2 version.

testcases/kernel/hotplug/{cpu_hotplug,memory_hotplug}/COPYING mention:
"These tests are OSDL/LF and imported into LTP under GPLv2."

testcases/open_posix_testsuite/COPYING has extra BSD 2-clause license + other
test at the top:

All sourcecode generated from scratch by Ngie Cooper is BSD 2-clause
licensed. All legacy openposix test suite code is GPLv2+ licensed.

You must honor the respective license when copying code.

BSD 2-clause license:
...

I suppose it's safe to keep only single licence in testcases/open_posix_testsuite/,
but could we keep only COPYING in the root directory and delete the rest?
Or keep COPYING and testcases/open_posix_testsuite/COPYING only?

Kind regards,
Petr
