Andrii Nakryiko fe92833524 libbpf: Fix uprobe symbol file offset calculation logic 
Fix libbpf's bpf_program__attach_uprobe() logic of determining
function's *file offset* (which is what kernel is actually expecting)
when attaching uprobe/uretprobe by function name. Previously calculation
was determining virtual address offset relative to base load address,
which (offset) is not always the same as file offset (though very
frequently it is which is why this went unnoticed for a while).

Fixes: 433966e3ae ("libbpf: Support function name-based attach uprobes")
