scripts/faddr2line: Fix vmlinux detection on arm64
[ Upstream commit b6a5068854cfe372da7dee3224dcf023ed5b00cb ]
Since commit dcea997beed6 ("faddr2line: Fix overlapping text section
failures, the sequel"), faddr2line is completely broken on arm64.
For some reason, on arm64, the vmlinux ELF object file type is ET_DYN
rather than ET_EXEC. Check for both when determining whether the object
is vmlinux.
Modules and vmlinux.o have type ET_REL on all arches.
