sysdeps/init_array: Add PREINIT_FUNCTION to crti.S
The RISC-V port contains a crti.S that simply contains a link to
PREINIT_FUNCTION (when defined). As this should be entirely generic,
Joseph Myers suggested that we update the generic init_array version to
contain this. Since RISC-V is the only user of init_array this won't
break any existing ports.

* sysdeps/init_array/crti.S (.section .init_array): Add
PREINIT_FUNCTION when defined.
