gpiolib: Disable compat ->read() code in UML case
It appears that UML (arch/um) has no compat.h header defined and hence
can't compile a recently provided piece of code in GPIO library.
Disable compat ->read() code in UML case to avoid compilation errors.
While at it, use pattern which is already being used in the kernel elsewhere.
Fixes: 5ad284ab3a01 ("gpiolib: Fix line event handling in syscall compatible mode")
