selftest mm/mseal: fix test_seal_mremap_move_dontunmap_anyaddr
the syscall remap accepts following:
mremap(src, size, size, MREMAP_MAYMOVE | MREMAP_DONTUNMAP, dst)
when the src is sealed, the call will fail with error code:
EPERM
Previously, the test uses hard-coded 0xdeaddead as dst, and it
will fail on the system with newer glibc installed.
This patch removes test's dependency on glibc for mremap(), also
fix the test and remove the hardcoded address.
