Subject: app: Don't second-guess the dependency system
Removing this check makes the treatment of LittleCMS consistent with
all the other dependencies checked in the same file, which only check
that the runtime version is at least the required version.
As long as we were compiled against LittleCMS >= 2.8, and are now
running against a version that has at least the same symbols, it doesn't
necessarily matter whether the version we are running against is the
same one we were compiled against.
Distributions like Debian and Ubuntu track the versions in which
individual symbols were introduced, which allows runtime dependencies
to be weakened when no newer symbols are actually used; this is
practically necessary when working with very large numbers of packages,
to avoid a new version of a dependency library unnecessarily blocking
upgrade of dependent packages. However, this doesn't work if dependent
packages add their own checks that bypass this mechanism.
