linux, dump_syms: Filter module entries outside specified ranges
Partitioned libraries generated with lld and llvm-objcopy currently
contain a superset of debug information, beyond what applies to the
library itself. This is because objcopy cannot split up debug
information by partition - instead, it places a copy of all debug
information into each partition.
In lieu of potential future support for lld or objcopy becoming able to
split up debug information, let dump_syms do the next best thing:
- Find the address ranges of all PT_LOAD segments in the lib.
- Supply these to the Module being generated.
- Filter additions to the Module based on these ranges.
