hppa: add fanotify_mark

Another example of all the 64bit arches getting the definition via a
common file, but the 32bit ones all adding it by themselves and hppa
was missed.

I'm not entirely sure about the usage of GLIBC_2.19 symbols here.
We'd like to backport this so people can use it, but it means we'd
be releasing a glibc-2.17/glibc-2.18 with a GLIBC_2.19 symbol in it.
But maybe it won't be a big deal since you'd only get that 2.19 ref
if you actually used the symbol ?

There hasn't been a glibc release where hppa worked w/out a bunch of
patches, so in reality there's only two distros that matter -- Gentoo
and Debian.
