[release/7.0] Fix parsing the output of ping on Samsung phones

[github-actions]

Backport of #80133 to release/7.0

Fixes #78990

/cc @simonrozsival

Customer Impact

Some Android installations contain a ping utility that produces slightly different output when TTL is exceeded from what our code expects. This seems to be the case at least on Samsung phones. This PR updates the parser to account for this variation.

Testing

• Manual testing on a Samsung phone (API 31) and on Android emulators of various API levels.
• CI - Android emulator (API 29)

Risk

Low.
