[llvm] [LLVM][test][nfc] Prefixing JITDUMPDIR environment variable with env (PR #98370)

[via llvm-commits]

https://github.com/connieyzhu created https://github.com/llvm/llvm-project/pull/98370

The RUN line attempts to set the JITDUMPDIR environment variable, which fails in llvm-lit's internal shell. This patch prefixes JITDUMPDIR with env so that the behavior of setting the variable is as expected in the internal shell.
