liblog: __android_log_pmsg_file_write() cleanup
__android_log_pmsg_file_write() will open /dev/pmsg0 if not
already, and will close it if we opened it.
Added atomic access to the android_log_context as insurance.
Fortify and correct pmsg tests.
Test: gTest liblog-unit-tests --gtest_filter=liblog.__android_log_pmsg_file_*
