mm: uninline kstrdup()

gcc inlines kstrdup into kstrdup_const() but it can very efficiently tail
call into it instead:

$ ./scripts/bloat-o-meter ../vmlinux-000 ../obj/vmlinux
add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-84 (-84)
Function                                     old     new   delta
kstrdup_const                                119      35     -84
