[DebugInfo] Fix reading location tables of v5 units in DWP. Without the patch, all version 5 compile units in a DWP file read location tables from the beginning of a .debug_loclists.dwo section. The patch fixes that by adjusting the reading offset the same way as for pre-v5 units. The section identifier to find the contribution entry corresponds to the version of the unit.

## The test checks that v5 compile units in package files read their
## location tables from .debug_loclists.dwo sections.
## See dwp-v2-loc.s for pre-v5 units.
