[configure] Add goo to turn on silent build

Automake 1.11 has a new feature that's all the rage these days.

It makes build output look like:

CC     plymouthd-ply-boot-server.o
CC     plymouthd-ply-boot-splash.o
CC     plymouthd-main.o
CCLD   plymouthd

instead of the usual field gcc gunk.

This commit turns it on for those who have it.
