brillo: Remove dependency on icu for Brillo.

Mediaserver requires an internationalization data file that is 22 MB.
Since Brillo is headless and runs in a resource constrained environment,
remove the dependency on this file for Brillo.

BUG=25792311
TEST=mediaserver runs without /system/usr/icu/icudt56l.dat file. Audio
     playback, recording, and decoding work.
