Don't use MREMAP_DONTUNMAP on host when kernel < 5.13
If the kernel version on host is < 5.13 then it doesn't support
MREMAP_DONTUNMAP feature of mremap. In that case don't use it and
instead mmap the moving space again.
On target this can't happen as it's a prerequisite for userfaultfd.
Test: ART_USE_READ_BARRIER=false art/test/testrunner/testrunner.py --host
