tplink-safeloader: add support for TP-Link Archer A7 v5 (RU)

Although provided in separate zip archives, the firmwares for EU
and RU version are byte-identical. This adds the missing ID compared
to the support-list in the vendor firmware.

Note (since I checked it anyway):

Partitions and support list are unchanged for all three existing
firmware versions:

  * 20200721-rel40773
  * 20201029-rel43238
  * 20201120-rel50399
