Consider Xcode console as not a tty

When running gn_unittest under Xcode, isatty(1) returns true but
the ANSI escape sequences are not supported, resulting in weird
output.

Try to detect whether the output is send to Xcode's console by
checking whether some of the environment variables set by Xcode
are present.

Bug: none
