perf jit: Add NT_GNU_BUILD_ID definition for older distros
Such as CentOS5, where such define is not present in elf.h. This file, genelf.c, wasn't being built for several systems, because it mistakenly was conditional on some DWARF features, now that it is just needing libelf, after "perf jit: Enable jitdump support without dwarf" it fails. So, as preparation for "perf jit: Enable jitdump support without dwarf", conditionally define it, if not available.
