mm: increase the default mlock limit from 32k to 64k

By default, non-privileged tasks can only mlock() a small amount of
memory to avoid a DoS attack by ordinary users.  The Linux kernel
defaulted to 32k (on a 4k page size system) to accommodate the needs of
gpg.

However, newer gpg2 needs 64k in various circumstances and otherwise
fails miserably, see bnc#329675.

Change the default to 64k, and make it more agnostic to PAGE_SIZE.
