Subject: allow meson to find ICU in non-standard localtion

I attached a simple patch that allows meson to find ICU in a non-
standard location if if you specify -Dextra_lib_dirs and
-Dextra_include_dirs.

I'm not sure it's the right thing to do though. One downside is that it
doesn't output the version that it finds, it only outputs "YES".
