libxcb: fix rebuild when MACHINE changes

This recipe was patching the sysroot path directly into configure.ac, which
fails when the same source tree is re-used for another machine.

Instead, patch in $PKG_CONFIG_SYSROOT_DIR which is already exported for use by
pkg-config.

Also remove some commented-out lines that have no purpose.
