[Sanitizer][RISCV] Fix redefinition of REG_SP

Authored by luismarques on Nov 6 2020, 6:11 AM.



The include header sys/ucontext.h already defines REG_SP as 2, causing redefinition warnings during compilation. This patch fixes that issue.
(We also can't just use the numerical definition provided by the header, as REG_SP is used in this file this refers to a struct field.)
