[PATCH] tools/testing/kunit/kunit.py: remove redundant double check

[Alexander Pantyukhin <apantykhin@gmail.com>]

The build_tests function contained the doulbe checking for not success
result. It is fixed in the current patch. Additional small
simplifications of code like useing ternary if were applied (avoid use
the same operation by calculation times differ in two places).
