Log Message:
databases/libzdb: make this build on 32-bit NetBSD hosts.

Add two patches:
 * Avoid c++ overload conflict between `time_t` and `long long`
 * Fix a print of `time_t` in tests/unit.c.

It seems evaldo@gardenali.biz was swallowed by Google 10+ years
ago (domain gardenali.biz no longer exists), so I took the liberty
of reverting that to pkgsrc-users@NetBSD.org.

Bump PKGREVISION.
