s390/pkey: Build module name array selectively based on kernel config options
There is a static array of pkey handler kernel module names
used in case the pkey_handler_request_modules() is invoked.
This static array is walked through and if the module is not
already loaded a module_request() is performed.
This patch reworks the code to instead of unconditionally
building up a list of module names into the array, only the
pkey handler modules available based on the current kernel
config options are inserted.
