--disable-profiling does not disable profiling

The `--help` text says that `--disable-profiling` disables both executable and library profiling. But it doesn't seem to; for me, `cabal v2-build --disable-library-profiling --disable-executable-profiling` and `cabal v2-build --disable-profiling` produce different results -- the former disables profiling while the latter doesn't.

This may be related to #7314, but the symptoms I describe here are not quite the same as there: this is not a discrepancy between command line and config file, but between two command lines. Nevertheless, I do have `library-profiling: True` and `executable-profiling: True` in my `~/.cabal/config`, and that may be relevant.
