libsanitizer: Intercept __makecontext_v2 on Solaris/SPARC [PR113785]

As detailed in PR sanitizer/113785, this happens because an ABI change
in Solaris 10/SPARC caused the external symbol for makecontext to be
changed to __makecontext_v2, which isn't intercepted.
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.
