1. configuration: fix handling relative executables …

   Commit 720eb98 (configuration: refactorize code scanning for
   executables) introduced a bug when the executable is a relative path.
   In this case the file is always expanded, thus causing file to be always
   considered non executable by the code scanning through the parameters
   in configuration.cc.
   
   Update the look_path function to first try a file without consulting
   the PATH environment variable.
   
   Add the find_executable function, and update the code to check the file
   is not a directory instead of checking if it is a regular file, so that
   symlinks are handled correctly.
   
   Update the peek_file function to do the same, so that ParseManager can
   handle symlinks correctly.
   
   The old code worked because the last argument (before the executable
   arguments) was update correctly thanks to the loop over the PATH
   environment variable.
   
   Note that the correct solution is to add "--" before the executable
   arguments, but this will break the kcov cli interface.
