LU-16113 build: Fix configure tests for lock_page_memcg

Linux commit v5.15-12273-gab2f9d2d3626
   mm: unexport {,un}lock_page_memcg

Fails when lock_page_memcg exists but is not exported.

Adjust usage of [un]lock_page_memcg() to vvp_[un]lock_page_memcg() and
define the mapping accordingly to avoid the compile error.
