ppp: update to version 2.4.8.git-2020-05-25

ddd57c2 pppd: Add lcp-echo-adaptive option
c319558 pppd: Handle SIGINT and SIGTERM during interrupted syscalls (#148)
0bc11fb Added missing options to manual pages. (#149)
b1fcf16 Merge branch 'monotonic-time' of https://github.com/themiron/ppp
c78e312 pppd: linux: use monotonic time if possible

Remove patch 121-debian_adaptive_lcp_echo as patch is upstream accepted
Remove patch 206-compensate_time_change.patch as timewrap issues are
solved by a patch making use of monotonic time

-pppd: Watch out for time warps
-
-On many embedded systems there is no battery backed RTC and a proper system
-time only becomes available through NTP after establishing a connection.
-
-When the clock suddenly jumps forward, the internal accounting (connect time)
-is confused resulting in unreliable data.
-
-This patch implements periodic clock checking to look for time warps, if one
-is detected, the internal counters are adjusted accordingly.
