This change does 2 things:
- Skip 2 tests: they are not actually _testing_ anything, just running functions
Let's skip these for now until we can dedicate some time to investigate what
should be tested here. This will also help the tests breath a little bit.
- Add a small sleep to the async test. This test needs a little breathing room so
the procs don't get stepped on. I think this is what is causing the master to
shut down sometimes during test runs:

The fix in #49002 was incomplete and when run on Debian, it hits a
`ValueError` when the RELEASE variable is a string with a decimal.
This change fixes the error.
The `test_grains_append_val_already_present` test can be flaky, especially on
CentOS 7 when it gets bogged down. Let's give the test a little breathing room
by adding a sleep so the grains.append calls don't stack up too quickly.
