[clang] [clang][test] Fix emulated-tls.cpp failure on LoongArch (PR #208886)

[via cfe-commits]

https://github.com/wangleiat created https://github.com/llvm/llvm-project/pull/208886

The LoongArch backend does not support emulated TLS, so
mark the test as unsupported to fix the LoongArch buildbot
failure.

Failure: https://lab.llvm.org/staging/#/builders/20/builds/28875
