Ports: Prefer host python3.xx over python3

Browse source 
Previously we relied on the presence of a `python3` binary in the
PATH that has the correct minor version to build the port.

We now first check for the presence of a `python3.minor` binary
in the PATH and use that if found.

This allows users that have multiple Python versions installed
simultaneously (like from a PPA) to build the port without having
to change their main version.
