devel/apr1: Update to 1.6.3.1.6.1

[Bernard Spil]

Hi all,

There's an updated APR and APR-util released (1.6.3 and 1.6.1 
respectively).

I've updated the port (see patch) and used it to build for my local 
system without issues.

1. Build locally [OK]
2. `make test` -> "All tests passed." [OK]
3. Poudriere bulk 10.3 & 11.0 both i386 & amd64 [OK]

Find the port in my personal git repo at
https://github.com/Sp1l/freebsd-ports

Would you do any other QA checks?

Cheers,

Bernard.
