ANDROID: Have menuconfig sort microdroid defconfigs

Menuconfig has its own way of sorting defconfig files, and it is the
only tool that should be used for editing defconfig files. Use
menuconfig on the microdroid files to avoid configs moving around
when editing configs in the future.

No functional change. Verified by comparing vmlinux binaries before
and after this commit.
