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.
