Remove unused function is_gzip_supported().

Browse source 
This patch removes the unused `is_gzip_supported()` and changes the
documentation string around the `compress_method_t` enumeration to
explicitly state that both `ZLIB_METHOD` and `GZIP_METHOD` are both
always supported.

Zlib version 1.2.0 was released on the 9'th of March, 2003 according to
their ChangeLog.

See https://bugs.torproject.org/21663
