Nicolas Dichtel f8d858e607 xfrm: make user policy API complete ...

>From a userland POV, this API was based on some magic values:
 - dirmask and action were bitfields but meaning of bits
   (XFRM_POL_DEFAULT_*) are not exported;
 - action is confusing, if a bit is set, does it mean drop or accept?

Let's try to simplify this uapi by using explicit field and macros.

Fixes: 2d151d3907 ("xfrm: Add possibility to set the default to block if we have no policy")
