linker: make debug monitor isr symbol weak

Browse source 
It seems that currently it's impossible to create a custom
implementation for debug monitor exception without updating the vector
table (z_arm_debug_monitor maps to fault).
My proposition is to make this symbol weak, so that it can be overriden.
