DEBUG: mux-h2/flags: fix list of h2c flags used by the flags decoder

The two recent commits below each added one flag to h2c but omitted to
update the __APPEND_FLAG macro used by dev/flags so they are not
properly decoded:

  3dd963b35 ("BUG/MINOR: mux-h2: fix http-request and http-keep-alive timeouts again")
  68d02e5fa ("BUG/MINOR: mux-h2: make up other blocked streams upon removal from list")

This can be backported along with these commits.

(cherry picked from commit 55d2fc0c02103841725354cbba97d33f73c6ff4e)
