Build: call tools/version with sh

As tools/version has a shebang line, it should be
fine to just call it without specifying bash.

Calling bash explicitly may lead to inconsistency,
as the first line of tools/version indicates /usr/bin/sh
but the script is always executed with bash.
And, it adds bash as a new build dependency.
