Dmitry Safonov f80fd3a5ff selftests/x86: Add vDSO mremap() test
Should print this on vDSO remapping success (on new kernels):

 [root@localhost ~]# ./test_mremap_vdso_32
	AT_SYSINFO_EHDR is 0xf773f000
 [NOTE]	Moving vDSO: [f773f000, f7740000] -> [a000000, a001000]
 [OK]

Or print that mremap() for vDSOs is unsupported:

 [root@localhost ~]# ./test_mremap_vdso_32
	AT_SYSINFO_EHDR is 0xf773c000
 [NOTE]	Moving vDSO: [0xf773c000, 0xf773d000] -> [0xf7737000, 0xf7738000]
 [FAIL]	mremap() of the vDSO does not work on this kernel!
