postgis: Update to 3.0.2

pkgsrc changes: Adjust API_DEPENDS to 2.0.  I don't have a specific
reason, but the previous 1.4 is so ancient that accepting it defies
the Principle of Least Astonishment.

Note that regression tests crash, but in the same way as 3.0.1.
3.0.1, when committed, passed, and I believe this is about proj.
