databases/mongodb32: Update to 3.2.3

- Update PORTVERSION and distinfo checksum (3.2.3) [1]
- Depend explicitly on Clang 3.7
- Update ONLY_FOR_ARCHS{_REASON} to exclude i386

Removes i386 support entirely, as even now I get pkg-fallout due to
mozjs failing to build in some circumstances, and the maintenance
burden isn't worth it given 32bit is deprecated.

A future revision may conditionally check the existence of a global
clang that meets the requirements of this port, but right now that
requires fixing some issues in compiler.mk and I don't feel it
appropriate to replicate its entire functionality to fix this port for
now.
