* Fix: repeatedly dereference pom variables
Previously, if there was more than one layer of variable indirection in
the pom property (propert A says it has the same value as property B,
property B says it has the same value as property C), then Syft would
only dereference one layer. Add a loop to dereference variables until
either dereferencing fails, or until the variable is completely
dereferenced back to a literal.
