Subject: [PATCH 2/2] mount: add definition for FSOPEN_CLOEXEC
A recent change in glibc introduced `enum fsconfig_command` [1] and as a
result the compilation of criu fails with the following errors

This patch adds definition for FSOPEN_CLOEXEC to solve this problem. In particular,
sys/mount.h includes ifndef check for FSOPEN_CLOEXEC surrounding `enum fsconfig_command`.
