test-release.sh: Fix phase2 and phase3 binary comparision

[tstellar]

Summary

scudo_utils.cpp.o from compiler-rt had has one of the compiler's builtin
include paths stored in the .debug_line section. So we need to do
sed 's,Phase1,Phase2,g` on the Phase2 object file so it matches Phase3.

Apologies for the slow reply; I was on vacation.

lgtm, thanks for fixing this!

             # Substitute 'Phase2' for 'Phase3' in the Phase 2 object file in
             # case there are build paths in the debug info. On some systems,
             # sed adds a newline to the output, so pass $p3 through sed too.
