bpftool: Fix typo in struct_ops map FD generation for light skeleton

Browse Source 
When generating light skeletons for BPF programs containing struct_ops
maps, bpftool incorrectly outputs a stray literal 't' instead of a tab
character for the map file descriptor member in the links structure.
This causes a compilation error when the generated light skeleton is
used.

Correct the format string by replacing 't' with '\t'.
