[libc-commits] [libc] [libc][minor] Fix assertion in LlvmLibcFILETest.SimpleFileOperations (PR #126109)

[Alan Zhao via libc-commits]

https://github.com/alanzhao1 created https://github.com/llvm/llvm-project/pull/126109

The file descriptor of the first opened file is not necessarily 3, so we change the assertion so that it's >= 3 (i.e. not 0, 1, 2, or -1 which correspond to stdin, stdout, stderr, or error respectively.)

Fixes #126106
