zlib (gzfile_write_raw): do not resize string after .write call
Apparently, a component of Rails implements a buffering .write
method which keeps the String buffer around and makes it unsafe
for us to clear it after calling .write.
This caused Rack::Deflater to give empty results when enabled.
Fortunately, per r61631 / a55abcc0ca6f628fc05304f81e5a044d65ab4a68,
this misguided optimization was only worth a small (0.5MB) savings
and we still benefit from the majority of the memory savings in
that change.
Thanks to zunda for the bug report.
