linux: set a few more initramfs opts for newer kernels

Building with linux-2.6.36 and initramfs support causes the build to
pause while it prompts for newer options (uid/gid/compression).  So
have the build system inject the newer options into the linux config
automatically.  Older versions should just ignore these.
