Stop converting "=y" and "=m" to "true" for the raw feature values used
in "kernel.config" custom rule processing.
In practice, this means that to check if a kernel config flag has been
set to "y" or "m", one needs to explicitly check for both of the values:
matchFeatures:
- feature: kernel.config
matchExpressions:
FOO: {op: In, value: ["y", "m"]}
instead of (how it used to be):
matchFeatures:
- feature: kernel.config
matchExpressions:
FOO: {op: IsTrue}
The legacy kconfig custom rule is unchanged as are the
kernel-config.<flag> feature labels.
