[PATCH 4/9] Avocado: bump to version 95.0

[Cleber Rosa]

Even though there have been a number of improvements (and some pretty
deep internal changes) since Avocado 88.1, only one change should
affect "make check-avocado".

With the nrunner architecture, test execution happens in parallel by
default.  But, tests may fail due to insufficient timeouts or similar
reasons when run under systems with limited or shared resources.  To
avoid breakages, especially on CI, let's keep the serial execution
until proven that it won't impact the CI jobs.
