readme: Accept multiple candidates and test them.
The readme variable may now contain multiple space deliminated entries, which per usual are either a filepath or a git ref filepath. If multiple are specified, cgit will now select the first one in the list that exists. This is to make it easier to specify multiple default readme types in the main cgitrc file and have them automatically get applied to each repo based on what exists. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
