Add the missing header for `errno` variable in `checks.cc`

Variable `LAST_SYSTEM_ERROR` was introduced in https://webrtc-review.googlesource.com/c/src/+/32780.
It seems to be the same codeblock in `physicalsocketserver.cc`, only difference is it did not
include the header <errno.h>.

Also, probably a good idea to make the include conditional.
