Update parent to pom-scijava-base 21.1.0

This adds support for new scijava properties that allow to configure
extra VM arguments as well as JPMS-specific (i.e. Java 9+) arguments.
And the VM argument --add-opens=java.base/java.lang=ALL-UNNAMED is
included by default when Java 9+ is used, so that the ReflectionUnlocker
class of org.scijava:app-launcher can be used more easily to avoid
burdensome reflection restrictions on modularized Java code.
