Tarantool 1.9 support

[GhOsTMZ]

Hi,
I was install a memcached module and have this at startup tarantool:

2018-05-07 14:17:46.884 [10871] main/101/memcached.lua F> ./memcached.lua:49: loop or previous error loading module 'memcached'

Thanks!

I was rebuild memcached module with Tarantool 1.9 headers and have this at startup (used builded for 1.7 before):

2018-10-08 12:32:06.839 [10465] main/101/memcached expiration.c:114 E> Can't start the expire fiber

2018-10-08 12:32:06.839 [10465] main/101/memcached expiration.c:115 E> fio: No such file or directory

Update
This behavior possible if tarantool started by tarantoolctl (or systemd). Expiration fiber executes successfully if tarantool execute that:

tarantool /etc/tarantool/instances.available/memcached.lua
