libbpf: Fix output .symtab byte-order during linking
[ Upstream commit f896b4a5399e97af0b451fcf04754ed316935674 ]
Object linking output data uses the default ELF_T_BYTE type for '.symtab'
section data, which disables any libelf-based translation. Explicitly set
the ELF_T_SYM type for output to restore libelf's byte-order conversion,
noting that input '.symtab' data is already correctly translated.
Fixes: faf6ed321cf6 ("libbpf: Add BPF static linker APIs")
