[Buildroot] [PATCH] support/testing: import rootfs-overlay for systemd testsuite

[Romain Naour <romain.naour@gmail.com>]

comment PS1 customization: the testsuite require a non customized PS1

 # /usr/lib/systemd/tests/run-unit-tests.py
 PASS: test-acl-util
 PASS: test-af-list

La testsuite Buildroot se lance de cette mani?re et seul le test systemd est test?:
./support/testing/run-tests -o testsuite/ -k -d dl/ tests.package.test_systemd.TestSystemd
16:12:42 TestSystemd                              Starting
16:13:04 TestSystemd                              Cleaning up
.
----------------------------------------------------------------------
Ran 1 test in 22.384s

OK

Pour l'instant la testsuite de systemd n'est pas lanc?e automatiquement.
Il faut lancer le script:
  /lib/systemd/tests/run-unit-tests.py

On a besoin d'un niveau d'entropie suffisant pour certain tests.
On test avec cgroupv2
On test avec un kernel 5.4 LTS.

SKIP: test-barrier
SKIP: test-bus-chat

FAIL: test-execute

OK: 197 SKIP: 2 FAIL: 1
