[B][SRU][PATCH 0/2] selftests: Remove broken Power9 paste tests and fix compilation issue

[Po-Hsu Lin]

== SRU Justification ==
With the Power9 copy_unaligned test removed in bug 1813118,
we can now move forward and remove the broken paste_unaligned /
paste_last_unaligned test in selftests/powerpc.

>From the commit message:
    Paste on POWER9 only works to accelerators and not on real memory.
    So these tests just generate a SIGILL.

Actual test output:
    test: test_paste_unaligned
    tags: git_version:unknown
    !! child died by signal 4
    failure: test_paste_unaligned
    not ok 1..2 selftests: paste_unaligned [FAIL]
    selftests: paste_last_unaligned
    ========================================
    test: test_paste_last_unaligned
    tags: git_version:unknown
    !! child died by signal 4
    failure: test_paste_last_unaligned
    not ok 1..3 selftests: paste_last_unaligned [FAIL]
    selftests: alignment_handler

(On Power8 these two test will be skipped)

This patchset will also address the compilation intrduced by b2d35fa
(selftests: add headers_install to lib.mk) which landed with Bionic
upstream stable patchset 2019-07-12 (bug 1836426)

== Fix ==
* 525661ef (selftests/powerpc: Remove Power9 paste tests)
* 7e0cf1c9 (selftests/powerpc: Fix Makefiles for headers_install change)

These has been applied in Disco.

As Cosmic will reach EOL soon, and we don't have alignment tests in
Xenial, we only need this for Bionic.

== Test ==
Patch tested on a P9 node "baltar", test build OK and these two tests
were removed as expected.

== Regression Potential ==
Low.
Code change limited to testing tools for Power9 and just removing
broken tests, fix build error.
