layer.conf: fix syntax error in PATH setting

Commit 05a87be51b44608ce4f77ac332df90a3cd2445ef introduced
a Python conditional expression when updating PATH that
generates syntax warnings in bitbake-cookerdaemon.log:

  Var <PATH[:=]>:1: SyntaxWarning: "is not" with a literal. Did you mean "!="?

Fix this by using the more appropriate '!=' comparison
operator.
