build: link jemalloc by default to reduce heap fragmentation

Browse source 
The QML engine and the quickshell reloader both cause large amounts of
heap fragmentation that stacks up over time, leading to a perceived
memory leak. Jemalloc is able to handle the fragmentation much better,
leading to lower user facing memory usage.
