The pkey tests define a whole lot of functions and some global variables.
A few are truly global (declared in pkey-helpers.h), but the majority are
file-scoped. Make sure those are labelled static.
Some of the pkey_{access,write}_{allow,deny} helpers are not called, or
only called when building for some architectures. Mark them
__maybe_unused to suppress compiler warnings.
