build:  Add USE_SET_METADATA tag

On some of the older devices the recovery doesn't support
metadata when setting permissions.  This allows to use
set_perm vs set_metadata you will need to set
USE_SET_METADATA := false inside your boardconfig.mk

arm: Drop linker script when building without PIE

The current section headers generated by bionic are incompatible
with this (interp is in, ctors were dropped, and other tiny changes
related to Elf32_Dyn). But... we don't actually need this to
disable PIE, so drop it entirely instead of writing a new one.
