[PATCH 1/2] rust: arch/um: use 'static' relocation model for uml modules

[Zigit Zo]

In the x86_64 UML, kernel modules compiled with Rust will currently
generate some R_X86_64_GOTPCREL relocations, which will then be rejected
by the kernel.

And because of the kernel modules of UML are only got handled by the UML
itself, relocation model 'static' can work as expected other than 'pie'.
