tests,systemc: Fix nightly systemc test

Browse Source 
This fixes these nightly failing tests:
https://jenkins.gem5.org/job/nightly/609/

Due to this commit:
https://gem5-review.googlesource.com/c/public/gem5/+/68758
The source files are not copied to the "build" directory by default.
This caused the systemc tests to fail as the
"util/systemc/gem5_within_systemc/Makefile" depends on generated source
files in the "build" directory.

This patch adds the "--duplicate-sources" flag to the building of the
ARM binaries necessisary for running systemc. The README has been
updated to reflect this.

First build gem5 as a library with cxx-config support and (optionally)
without python. When building the library, disable gem5's native SystemC
API support, as that will conflict with the external version. Also build a
normal gem5 (cxx-config not needed, Python needed):
