Fix variable shadowing warning in logging on VS2015

d:\src\cr3\src\base\logging.cc(167): error C2220: warning treated as error - no 'object' file generated
d:\src\cr3\src\base\logging.cc(167): warning C4459: declaration of 'log_file' hides global declaration
d:\src\cr3\src\base\logging.cc(103): note: see declaration of 'logging::`anonymous-namespace'::log_file'

There was 3 different things called log_file in this file: a global FileHandle,
a local PathString, and a PathChar* member variable in LoggingSettings. :/

(Should probably rename all the globals to g_ prefixed in a followup.)
