ramips: mt7621: include uboot-envtools in some missed devices

Add uboot-envtools (removing -uboot-envtools) to devices which were
missed in the commit 79bd017 ("ramips: mt7621: add uboot-envtools to
all devices")

- Mi Router 3G
- Mi Router AC2100

While at here remove two redundant entries from devices which were added
just after the referenced commit 79bd017 and did not account for the
new DEFAULT_PACKAGES member:

- SNR-CPE-ME1
- SNR-CPE-ME2-SFP

Fixes: 79bd017 ("ramips: mt7621: add uboot-envtools to all devices")
