libsanitizer: Intercept __makecontext_v2 on Solaris/SPARC [PR113785]

The following patch, submitted upstream at https://github.com/llvm/llvm-project/pull/81588, fixes that. Tested on sparc-sun-solaris2.11 and i386-pc-solaris2.11. 2024-02-16 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> libsanitizer: PR sanitizer/113785 * asan/asan_interceptors.cpp: Cherry-pick llvm-project revision 8c2033719a843a1880427a5e8caa5563248bce78.
