alloc_tag: move memory_allocation_profiling_sysctls into .rodata 



Remove the change in file mode permissions done before initializing the
sysctl. It is not necessary as the writing of the kernel variable will
be blocked by the proc_mem_profiling_handler when writing is disallowed
(also controlled by mem_profiling_support).
