This is correct, and the generated wrapper (just checked, downloaded it
from the store) is doing:
exec "env" LC_ALL=C mongod --smallfiles --dbpath=$SNAP_COMMON "$@"

Is it the case as well for you? I just tried this and:

didrocks at tidus:~$ sudo snap run --shell rocketchat-server
root at tidus:/home/didrocks# env | grep SNAP_COMMON

So, it's set for me, CCing Zyga who might have an idea if there are some
cases where snap-confine doesn't set those variables…
