Fix .clang-tidy

camelLower is not a type, camelBack is.

Changes were made automatically with clang-tidy --fix-errors

To be able to apply changes automatically, the only way I've found that
works was to build the version of clang/clang-tidy that yocto has, and
run the fix script within bitbake -c devshell bmcweb.  Unfortunately,
yocto has clang-tidy 11, which can apparently find a couple extra errors
in tests we already had enabled.  As such, a couple of those are also
included.

Tested:
Ran clang-tidy-11 and got a clean result.
