liblog: add __attribute__((uninitialized)) to liblog buffers
These buffers are immediately written into with *printf() and are in
the hot path, so do not initialize them. This saves ~70ns off of each
log message, which is ~14% of the overhead within
__android_log_print() when writing to a no-op logger.
Test: liblog benchmarks
