tests: Enable config override for tests

Some tests require to change kconfig symbols values to cover the code.
This patch enables one to set these vaues using <test-name>-config
variable.

Example for integer values.
timestamp-test-config += CONFIG_HAVE_MONOTONIC_TIMER=1

Example for string values. Notice escaped quotes.
spd_cache-test-config += CONFIG_SPD_CACHE_FMAP_NAME=\"SPD_CACHE_FMAP_NAME\"
