6a9531a0f7 fix(userspace)!: show source config path only in debug builds
Starting from Falco 0.40, the `falco --help` output incorrectly showed
  the source config path (e.g., /home/runner/work/falco/falco/falco.yaml)
  in release packages. This path was intended only for local development.

  The issue was introduced when RelWithDebInfo build type support was
  added (commit 6bf33ffd). The existing code checked for BUILD_TYPE_RELEASE
  to determine release behavior, but RelWithDebInfo builds defined
  BUILD_TYPE_RELWITHDEBINFO instead, causing them to fall into the
  debug code path.

  This fix introduces BUILD_TYPE_DEBUG and changes the conditionals to
  enable dev features only when CMAKE_BUILD_TYPE is explicitly "debug".
  Both Release and RelWithDebInfo builds now correctly show only
  /etc/falco/falco.yaml.

  Fixes the regression introduced in 0.40.0
