Anas Nashif 5e591c38f1 kernel: do not export z_thread_priority_set 
This function is only being used by a test, so instead of reimplementing
a syscall in the test, provide a Kconfig option to provide the
functionality that only works with tests and remove some of the
duplication and extra code.

Title: Kernel Object Performance

Description:

The app_kernel test is used to measure the performance of the following
kernel objects: message queues, semaphores, memory slabs, mailboxes and pipes.

When the userspace version is selected (CONF_FILE=prj_user.conf), this
benchmark will execute with four configurations (kernel/kernel, kernel/user,
user/kernel and user/user). However, any configuration involving user threads
will omit both the memory slabs and mailbox tests.
