Log Message:
lint: correctly set system-header flag on cast-expression

When a cast-expression comes partly from a system header, determine at
the ')' whether the whole cast-expression comes from the system header.
Previously, it was based on the operand, which contradicted the
documentation of tn_sys.

Mainly affects strict bool mode (where expressions from system headers
are handled more leniently), as well as query 9 for parenthesized return
expressions.

Discovered upon manual inspection, as calling expr_alloc_tnode should
never be necessary when creating an expression node with operands;
there's build_op for that purpose.
