[PATCH v4 6/7] kprobes: Use text_alloc() and text_free()

[Jarkko Sakkinen <jarkko.sakkinen@linux.intel.com>]

Use text_alloc() and text_free(). Those arch's that provide their
allocators will benefit from this because they can provide their custom
allocator and render out the compile time dep to the module subsystem.
Other arch's will continue to work as the fallback implementations call
module_alloc() and module_memfree().
