[PATCH 2/1] Revert "t/lib-git-daemon: record daemon log"

[Thomas Gummerer <t.gummerer@gmail.com>]

This reverts commit 314a73d658 (t/lib-git-daemon: record daemon log,
2018-01-25), which let tests use the output of git-daemon.

The previous commit removed the last user of deamon.log in the tests,
there's no good way to make checking for output in the log
race-proof.  Revert this commit as well, to make sure others are not
tempted to use daemon.log in tests in the future, which would lead to
racy tests.

The original commit had one change that still makes sense, namely
switching read/echo for "read -r" and "printf", which relays the data
more faithfully.  Don't revert that piece here, as it is still a
useful change.
