Some boards have the environment variables defined in a slow EEPROM. post_run
accesses these environment variables to define which tests have to be run (in
post_get_flags). This is very slow before the code relocation on some boards
with a slow I2C EEPROM for environement variables.
This patch adds a check at the beginning of post_run to avoid to run
post_get_flags (which may be slow on some boards for the above reason) for some
given POST flags if no tests are defined with these flags (for instance, no need
to run POST tests with POST_ROM if no tests for POST_ROM are defined).
