  [ELF] Enable checkDynamicRelocsDefault for PPC64

.plt and .branch_lt have the type of SHT_NOBITS and may be relocated by dynamic
relocations with non-zero addends. They should be skipped for the
--check-dynamic-relocations check, as --apply-dynamic-relocs does not apply.

A side effect is that -z rel does not work for the two sections.

Added two --apply-dynamic-relocs --check-dynamic-relocations tests. Also checked
linking a PPC64 clang.
