Add a mutex to BoltDB state to prevent lock issues
Per https://www.sqlite.org/src/artifact/c230a7a24?ln=994-1081,
POSIX file advisory locks are unsafe to use within a single
process if multiple file descriptors are open for the same file.
Unfortunately, this has a strong potential to happen for
multithreaded usage of libpod, and could result in DB corruption.
To prevent this, wrap all access to BoltDB within a single
libpod instance in a mutex to ensure concurrent access cannot
occur.
