databases/postgresql-client unable to find pkgsrc libuuid

[Peter Lai <cowbert%gmail.com@localhost>]

On AWS Linux 2, both databases/postgresql12-client and
databases/postgresql13-client are unable to build without native
libuuid-devel installed.

the AWS Linux 2 native compiler is gcc 7.3.1, nothing in default
environment appears out of order

here is the pkgsrc mk.conf, all deps were built with this mk.conf:
