Tolerate missing line records in prologue search

If we're trying to scan line records for the function prologue, but the
current CU fails dwarf_getsrclines(), then just return so we can probe
without skipping prologues.

Such CUs were seen for the jemalloc sources built into Rust's libstd.
For some reason these don't have any DW_AT_stmt_list at all!
