    ktest: Fix ktest confusion with CONFIG_MODULES_USE_ELF_RELA
    
    In order to decide if ktest should bother installing modules on the
    target box, it checks if the config file has CONFIG_MODULES=y. But it
    also checks if the '=y' part exists. It only will install modules if the
    config exists and is set with '=y'. But as the regex that was used
    tests:
    
      /^CONFIG_MODULES(=y)?/
    
    this will also match:
    
      CONFIG_MODULES_USE_ELF_RELA
    
    as the '=y' part was optional and it did not test the rest of the line.
    When this happens, ktest will stop checking the rest of the configs but
    it will also think that no modules are needed to be installed. What it
    should do is only jump out of the loop if it actually found a
    CONFIG_MODULES that is set to true.
    
    Otherwise, ktest wont install the necessary modules needed for proper
    booting of the test target.
