=== Description (from pull-request) ===
When building `ruby-lxc` with LXC 3.0, I encountered the following error:
```
compiling lxc.c
In file included from
/nix/store/r3hkmi5r6ar270bsqlk9cha3fd4hc62w-lxc-3.0.0/include/lxc/lxccontainer.h:31:0,
from lxc.c:4:
lxc.c: In function ‘lxc_attach_parse_options’:
lxc.c:572:41: error: ‘EBADF’ undeclared (first use in this function)
lxc_attach_options_t default_opts = LXC_ATTACH_OPTIONS_DEFAULT;
```
It can be fixed simply by including `errno.h`.
