linux-user/sparc: Use WREG_SP constant in sparc/signal.c
s/UREG_FP/WREG_SP/g This is non-obvious because the UREG_FP constant is fact wrong. However, the previous search-and-replace patch made it clear that UREG_FP expands to WREG_O6, and we can see from the enumeration in target/sparc/cpu.h that WREG_O6 is in fact WREG_SP, the stack pointer. The UREG_SP define is unused; remove it.
