base-files: add mtd_get_mac_uci_config()

Browse Source 
Add mtd_get_mac_uci_config() for reading a MAC address from a UCI-style
config stored in an MTD partition. This is needed to support the
TP-Link ER605 v1; the existing UBI helper already covers the ER605 v2.
Also refactor common sed logic into a shared helper used by both
variants and drop the redundant cat pipe.

TP-Link ER605 v2 device support is unaffected. The one and only MAC
address on the tddp partition for v1/v2 is the label MAC address.
