libcrypt no longer supports setting our own threading callbacks, and is thread-safe if we call gcry_check_version() before creating threads. Unfortunately we can't guarantee that we call gcry_check_version() early enough, we try our best. Most of the callers of libsecret either don't use libgcrypt, or also initialize it appropriately themselves. Bump libgcrypt dependency to 1.4.5+, and have earlier versions use the native pthread implementation of locking.
