edk2: update to use "make" from prebuilts.

According to platform/build/+/master/Changes.md, restricted to use
external host tools (PATH) inside the build. Instead of invoking
"make" from the PATH invoke from a prebuilts location.

The Android build system no longer allows invocation of "make" from the path,
which produces the build error: "make" is not allowed to be used.
