fix(tests): don't perform crypto self-tests on boot

With the Kconfig update in commit 8a7e8a0,
CONFIG_CRYPTO_MANAGER_DISABLE_TESTS was changed from `y` to `not set`.
Crypto self-tests are required as part of the FIPS-enabled boot tests
and we will use the same Kconfig for testing FIPS-enabled VMs, so
instead of disabling tests at config level again, we set
`cryptomgr.notests` kernel boot arg to skip them.

To validate the fix, A/B tests were run:
- Firstly with the Kconfig option set to `y` vs `not set` to validate
  the regression
- Then with the boot arg set, to validate that the regression
  disappears
