Add more ePDG IP subnets to the default routes exclusions

[ameshkov]

Was having trouble getting Wi-Fi calling to work while using AdGuard but I stumbled upon this post on how to fix it. (Smart Philippines) Sharing the folllowing ePDG IPs used by our carriers here in the Philippines for Wi-Fi calling activation:

// epdg.epc.mnc003.mcc513.pub.3gppnetwork.org
// SMART Philippines Wi-Fi calling
203.87.172.0/24
121.54.55.0/24

// weconnect.globe.com.ph (Globe uses a different domain for their ePDG servers. Similiar to how AT&T does it)
// Globe Philippines Wi-Fi calling
112.198.111.0/24

// epdg.epc.mnc066.mcc513.pub.3gppnetwork.org
// DITO Telecommunity Wi-Fi calling
131.226.94.0/24
131.226.92.0/24
