dpkg: Search for debsig-verify in PATH instead of using an absolute path
Check that the command exists in the PATH before using it. This makes it
future proof, and friendlier to other systems that might not be using
the same filesystem layout.
It also makes it possible to use a local debsig-verify in a path such as
/usr/local/bin.
