elf: implement kmod_module_get_dependency_symbols()
...
Uses kmod_elf_get_dependency_symbols() that looks into ".symtab" for
UNDEF symbols and matches the name from ".strtab" to "__versions" to
get crc.
Likely the public API should unify the symbol information getters and
list release, they are almost the same.

elf: add get_symbols()
...
Similar to module-init-tools load_symbols(), it will try .symtab and
.strtab for symbols starting with __crc_, if they are found their crc
is read from ELF's Elf_Sym::st_value.
If not found, then it will fallback to __ksymtab_strings.

elf: fix regression with empty strings
...
Commit "b20dc17 Remove unneeded reference to last string" reverted the
fix in "47a0ef6 elf: do not output empty strings." and empty strings are
appearing again in kmod-modinfo.
With this commit we do a bit different and instead of keeping the
reference to last string we skip the '\0' inside the loop.

Cache the offset of crc
...
This way we don't need to check every time in loop. Indeed compiler
could already optimize out that checks, but this ways is cleaner and
shorter.

elf: skip leading symbol dot in modversion.

Mimics module-init-tools's dump_modversions() that calls skip_dot()
to skip leading dots. This is required for PPC64.
