LOG: [JITLink] Add explicit conversion to silence warnings / errors on bots.

Commit 10b5fec2563 uses a char -1 value, which triggers narrowing conversion
warnings / errors on some platforms (see e.g.
https://lab.llvm.org/buildbot/#/builders/36/builds/30312). Adding an explicit
conversion should fix this.
