Remove LOCAL_MODULE_TAGS := debug

Remove LOCAL_MODULE_TAGS := debug

Instead, su has been added to PRODUCT_PACKAGES_DEBUG in
build/make/target/product/base_system.mk

memeater didn't appear to have anything that needed it in every eng
build, so I've just removed the tag. If it's necessary, add it to the
list above.

I removed LOCAL_MODULE_TAGS and LOCAL_MODULE_PATH from libsimpleperf, as
static libraries are not impacted by either setting.
