mcctrl: Switch Linux functions/structures according to the version

Browse Source 
For get_user_pages_remote in binfmt_mcexec.c:
In 4.10 with 5b56d49fc31d ("mm: add locked parameter to
get_user_pages_remote()")
In 4.9 with 9beae1ea8930 ("mm: replace get_user_pages_remote()
write/force parameters with gup_flags")

For vmf in syscall.c, these two patches in 4.10:
82b0f8c39a38 ("mm: join struct fault_env and vm_fault")
1a29d85eb0f1 ("mm: use vmf->address instead of
vmf->virtual_address")
