[clang] [analyzer][NFC] Remove dangling method declaration from ErrnoChecker (PR #110820)

[Donát Nagy via cfe-commits]

https://github.com/NagyDonat created https://github.com/llvm/llvm-project/pull/110820

Remove the declaration of `ErrnoChecker::checkBranchCondition()` because this method is not defined or used anywhere. (It's probably a leftover from some old refactoring.)
