fix incorrect lineno in supp error msgs+ -v give filename+lineno of used supp. 

If a suppression file contains an error, the lineno reported could be wrong.
Also, give filename and lineno of the used suppressions in -v debugging output.

The fix consists in ensuring that tool specific read_extra function gets
the Int* lineno pointer, together with other VG_(get_line) parameters.
