Resolve Windows conflict between zlib and angle

Windows normally defines macros so that FAR expands to far, and
far expands to nothing.

Angle undefs far, leaving the FAR macro hanging, expanding to far
which is not a legal keyword anymore. zlib already tries to handle
that someone/something has undefined FAR but it doesn't handle
that someone/something has undefined far. This patch changes that.

This problem appeared in some jumbo builds in
gpu/command_buffer/service which uses both angle and zlib.
