libelf: Add n_namesz offset overflow check to gelf_get_note. During fuzzing of the new xlate_notes testcase I noticed that gelf_get_note didn't check whether the n_namesz of a note was too big. This could lead to offset wrapping around. Causing an infinite loop going over all ELF notes. Fix by adding an overflow check before updating offset. Signed-off-by: Mark Wielaard <mark@klomp.org>
