binman: bintool: parametrize args to pass to binary for returning version

The code to check the version is very similar between binaries, the most
likely only needed variables are the regex to find the version (already
supported) and the args to pass to the binary so that it prints this
version (e.g. --version, -V or similar).

Let's make it a parameter of Bintool so that code duplication can be
avoided for simple changes.
