[X][B][D][SRU][PATCH 0/2] Fix for efivarfs test on second run

[Po-Hsu Lin]

== SRU Justification ==
If you run the test selftest/efivarfs test suite twice, it will fail on
the second run.

This is because the test file created in the first run will obtain the
immutable property, and it will make the second attempt failed with
premission denied error.

== Fix ==
* 1f0ea958 (selftests: efivarfs: return Kselftest Skip code for skipped tests)
* dff6d2ae (selftests/efivarfs: clean up test files from test_create*())

This issue exists in X/B/D, fixed in newer releases.

For Xenial it lacks the crucial commit which allows the selftest
framework to handle KSFT_SKIP return code (3f4435b5), so the first
commit has to be backported to keep using 0 as its return value. The
second commit is a backport with fuzzy adjustments.

For Bionic, the first commit is a clean cherry-pick, the second is a
backport with fuzzy adjustments.

For Disco, it just needs the second commit, which is also a backport
with fuzzy adjustments as well.

== Test ==
Patch tested against the affected kernels, and it works as expected.

== Regression Potential ==
Low, changes limited to testing tools.
