gdb-index: Wire up str_offsets section to avoid incorrect error message about offsets_base

Browse Source 
There's still a need for a deeper fix to the way libDebugInfoDWARF error
messages are propagated up to lld - if lld had exited non-zero on this
error message we would've found the issue sooner.

# FIXME: Remove this once lld correctly returns non-zero on errors like this
# There's no other behavior to test hidden behind this error - lld only parses
# the CU for the address ranges, it doesn't need to decode any strings.

## The code contains DWARF v5 sections .debug_rnglists and .debug_addr.
## Check we are able to build the correct address
