Anton Protopopov 277f9ffe87 libbpf: Use proper errno value in linker ...

[ Upstream commit 358b1c0f56 ]

Return values of the linker_append_sec_data() and the
linker_append_elf_relos() functions are propagated all the
way up to users of libbpf API. In some error cases these
functions return -1 which will be seen as -EPERM from user's
point of view. Instead, return a more reasonable -EINVAL.
