[pushed] Use 'bool' more idiomatically in dwarf_decode_lines

[pushed] Use 'bool' more idiomatically in dwarf_decode_lines

[Tom Tromey]

I noticed a couple of spots related to dwarf_decode_lines where the
'include_p' field was not being used idiomatically -- it is of type
bool now, so treat it as such.
