linux-user/arm/nwfpe: rename REG_PC to ARM_REG_PC

The REG_PC constant used in the ARM nwfpe code is fine in the kernel
but when used in qemu can clash with a definition in the host system
include files (in particular on Ubuntu Lucid SPARC, including signal.h
will define a REG_PC). Rename the constant to avoid this issue.
