Removes ifdefs in browser_render_process_host.cc that prevented

adding custom words to the dictionary on platforms other than 
windows. This functionality has now been implemented on all
platforms. Patch from pwicks86@gmail.com (Paul Wicks)
BUG=None
TEST=Adding words to dictionary on mac and linux.
