Fix EMPROFILE=1 toolchain profiler to not break if user passes an incorrect @rsp (#25125)

Fix EMPROFILE=1 toolchain profiler to not break if user passes an
incorrect @rsp file, but profile that command line as-is.

This way the incorrect @rsp file error will be properly raised from
within emcc, and not the toolchain profiler.
