Add configure --with-tmpfilesdir and lvm2 tmpfiles.d configuration file itself.

/etc/tmpfiles.d directory holds configuration files for temporary/volatile
files and directories that should be automatically managed. For example,
if we have some parts of the fs hierarchy on tmpfs, we'd like to recreate
some files or directories on every boot so they're always prepared for use.

Systemd can read such configuration files. For now, the lock and run directory
are the ones that are most probably placed on tmpfs. If this is the case, we
can install the configuration by 'make install_tmpfiles_configuration'.
