change test behavior.

# Setup env__saveenv_test_skip to True if saveenv test is not possible or
 | 
						|
# desired and should be skipped.
 | 
						|

# Setup env__saveenv_test to set the bootmode if 'modeboot' u-boot environment
 | 
						|
# variable is not set. Test will be skipped if bootmode is not set in both
 | 
						|
# places i.e, boardenv and modeboot u-boot environment variable
 | 
						|
