ld/testsuite: disable ilp32 tests for aarch64-qnx

aarch64nto32 emulation isn't supported. The tests will then fall back
on aarch64elf32. It does work but some extra warnings are being
generated because the "-z relro" being added aarch64nto but ignored by
aarch64elf32 emulation.
Skip the tests to avoid any problems.
