LU-8560 libcfs: handle page_cache_*() removal in newer kernels

Since page cache handling never was handled differently than
normal pages the page_cache_*() macros have been removed
starting with linux kernel 4.6. Now put_page() and get_page()
need to be used instead.

Second change is that get_user_page dropped the first two
arguments in linux kernel version 4.6. We handle this change
as well in libcfs.
