[U-Boot] [PATCH] Fix handling of some broken test expressions

Observed incorrect bahavior (some debug traces are enabled):

U-Boot# test = yes test(3): '=' 'yes': returns 0 U-Boot# test yes = test(3): 'yes' '=': returns 0

This means that any "if test" with such broken expressions (maybe due to an empty variable) in incorrectly evaluated as true.
