arm64: fix an issue with kaslr-enabled vmlinux
Normally vmlinux for arm64 is of ET_EXEC type, while if built with
CONFIG_RANDAMIZE_BASE (that is KASLR), it will be of ET_DYN type.
Meanwhile, physical address field of segments in vmlinux has actually
the same value as virtual address field.
Accordingly, in this case, it totally makes no sense to check for
validity of segments against physical memory ranges and, if necessary,
relocate them in elf_exec_load() on arm64.
This patch allows to unconditionally skip the check on arm64.
