Enforce pick-up of linux.riscv64 root-files in equinox.executable.feature

[HannesWell]

This allows to pick-up the new root-files for linux.riscv64 contributed via #669.

This should unblock eclipse-platform/eclipse.platform.releng.aggregator#2394 and should be reverted once that is submitted and has passed an I-build, together with

equinox/features/org.eclipse.equinox.executable.feature/pom.xml

Lines 94 to 107 in abde0eb

	<!-- Temporary work-around until gtk.linux.riscv64 environment is enabled in general. -->
	<plugin>
	<groupId>org.eclipse.tycho</groupId>
	<artifactId>target-platform-configuration</artifactId>
	<configuration>
	<environments combine.children="append">
	<environment>
	<os>linux</os>
	<ws>gtk</ws>
	<arch>riscv64</arch>
	</environment>
	</environments>
	</configuration>
	</plugin>

Without this the root files for linux.riscv64 are removed during baseline-replacement because tycho-p2-plugin:p2-metadata#baselineReplace has the value all by default, which means: Replace build artifacts with baseline version. Attached artifacts only present in the build are removed.

The reason this wasn't necessary for win32.aarch64 in #559 is probably because eclipse-platform/eclipse.platform.releng.aggregator#577 was submitted before the next I-build happened and therefore the different qualifier of the o.e.equinox.executable.feature prevented a baseline replacement.

Looks like this that didn't work after all, so I just went on with a simple enforced qualifier update for the o.e.equinox.executable.feature.

Verification with eclipse-platform/eclipse.platform.releng.aggregator#2394 succeeded.
