systemc: Fix systemc array bound error

Currently, gcc 10.0 does not compile gem5 due to an array bound error
in sc_unsigned and sc_signed constructors.

Previous fix only ignores array-bounds warnings for sc_unsigned.cc and
sc_signed for gcc 10.1 onwards.

This commit turns the ignoring array-bounds warning flag on for all
gcc 10 onwards.
