Removing wget in favor of curl

configs/releng/airootfs/root/.automated_script.sh:
Replacing wget with curl for the use-case of downloading a
pre-specified remote startup script (changing flags where needed).

configs/releng/packages.x86_64:
Removing wget from the list of installed packages, as
.automated_script.sh was the only reason for it being installed.

Closes #16
