systemc: remove boost header dependency

The current tests included don't require boost header to work. Remove
the dependency. This also gets rid of the warning message generated by
the latest boost headers.

Tested by running systemC tests:

src/systemc/tests/verify.py --update-json \
  --filter-file=src/systemc/tests/working.filt -j 56 build/ARM/
