Support kernels that backported kallsym functions from newer linux kernels

Some Linux distributions may have backported
module_kallsyms_on_each_symbol and kallsyms_on_each_symbol functions
from newer linux kernels.  In these situations checking the kernel
version would not detect the proper arguments for these functions.
Systemtap now has a couple of autoconf tests to determine what
arguments should be used for these functions.
