rpc: Add PKCS#11 module that connects to socket

This patch adds a PKCS#11 module that connects to the p11-kit server
exposed on the filesystem.  The filename of the socket is determined in
the following order:

- $P11_KIT_SERVER_ADDRESS, if the envvar is available
- $XDG_RUNTIME_DIR/p11-kit/pkcs11, if the envvar is available
- /run/$(id -u)/p11-kit/pkcs11, if /run/$(id -u) exists
- /var/run/$(id -u)/p11-kit/pkcs11, if /var/run/$(id -u) exists
- ~/.cache/p11-kit/pkcs11.

Note that the program loading this module may have called setuid() and
secure_getenv() which we use for fetching envvars could return NULL.
