Dominik Brodowski 2cbc0d66de selftests/x86: Do not rely on "int $0x80" in test_mremap_vdso.c 
On 64-bit builds, we should not rely on "int $0x80" working (it only does if
CONFIG_IA32_EMULATION=y is enabled).

Without this patch, the move test may succeed, but the "int $0x80" causes
a segfault, resulting in a false negative output of this self-test.
