RFR: 8289572: InputStream wrapping with BufferedInputStream is redundant in HttpTimestamper

Fri Jul 1 08:16:20 UTC 2022

In case we read all bytes from an `InputStream` we don't need wrapping with `BufferedInputStream` as the bytes are not written into internal buffer. With removal of redundant buffer we save 8 kB of allocated memory.
