Subject: [PATCH] dev: Reduce number of Travis MacOS builds to 2

This reduced build time, frequently to half, because Travis has a limit
of 2 concurrent builds:
"After much painstaking deliberation, we have decided to limit the
concurrent macOS builds to a maximum of two out of the five offered."

Fixes #332.
