Fix a warning in PhabricatorRepositoryCommit using an unary operation
Summary:
Avoid a static code analysis warning
`Unary operation "~" on mixed results in an error.`
by explicit casting $flag to an integer (which it should be anyways) before applying the bitwise operator.
Test Plan: Run static code analysis, get one complaint less.
