Userland: Add aliases to the macro in BuggieBox

Browse Source 
Before, the `ENUMERATE_UTILITIES` macro only included utilities, and all
the aliases to the utilities were explicitly handled. This patch
combines utilities and aliases into one macro. This has the benefit of
being able to do operations involving both utilities and aliases without
having to choose which group to operate on first. Currently, aliases are
mixed with utilities while maintaining alphabetical sort.
