Change ICU_UTIL_DATA_IMPL on Linux to match the reality.
We've bundled the ICU data file for 'ages' on Linux, but ICU_UTIL_DATA_IMPL on Linux
is still set to ICU_UTIL_DATA_FILE.
Apparently, this hasn't been noticed because u_setDataDirectory and
udata_setFileAccess just set the global variable pointing to the data file
location. This is not totally free because u_setDataDirectory does some
locking/unlocking.
BUG=NONE
TEST=Builds go through on Linux and binaries (chrome, test, etc) run just fine.
