Skip scanning the module path when running in a native image

Prior to this commit, the following exception was thrown when using the
PathMatchingResourcePatternResolver to scan for class path resources
using the `classpath*:` prefix within a native image.

com.oracle.svm.core.jdk.UnsupportedFeatureError: JRT file system is disabled
com.oracle.svm.core.util.VMError.unsupportedFeature(VMError.java:89)

org.springframework.core.io.support.PathMatchingResourcePatternResolver.lambda$findAllModulePathResources$6(PathMatchingResourcePatternResolver.java:819)

This commit addresses this by not attempting to scan the module path
when running in a GraalVM native image.

Closes gh-29183
