[Build] Don't resign already signed jars

Reduce the number of actual signing operations by not re-signing
artifacts (in the I-build) are already signed, usually because they have
been 'baseline-replaced'.

The baseline replacement is performed first the 'p2-metadata-default'
goal executed by default and before the jar-signing.
The subsequent explicit invocation of the p2-metadata (non-default) goal
is again necessary to update the p2 metadata (like artifact size) after
the jar has been altered by the signing operation.
