Minor Fuchsia-specific fix to base/test/perf_test_suite.cc

Perftest logging on fuchsia is broken. The changed file
manages locating and initializing a log file, specialized
for each platform. Previously, the file failed to
initialize a log file, because there was no fuchsia
specific clause in the Initialize() function, and the
default assumptions don't work on Fuchsia. The OS_ANDROID
clause also works for Fuchsia, so this change adds
it to that code path.
