libbpf: Add elf_resolve_pattern_offsets function
Adding elf_resolve_pattern_offsets function that looks up
offsets for symbols specified by pattern argument.
The 'pattern' argument allows wildcards (*?' supported).
Offsets are returned in allocated array together with its
size and needs to be released by the caller.
