scripts: Fix size_report to use correct objdump and nm

Browse source 
Commands for objdump and nm where hardcoded in size_report
script, which failed on MacOS as it tried to use ones from
Xcode. Fixed the script to pick the right objdump and nm
from the toolchain being used to build the application.
