[refpolicy] [PATCH 1/1] Allow openvpn temporary files

[refpolicy] [PATCH 1/1] Allow openvpn temporary files

[Sven Vermeulen]

When launching OpenVPN, it fails to start and the following error 
is displayed in the openvpn.log file:

Options error: Temporary directory (--tmp-dir) fails with '/tmp': Permission
denied

The AVC denial shows an attempt to read/write/search in tmp_t directory. A quick
check through the code does not show any attempts to create directories, only
temporary file, so create an openvpn_tmp_t with the proper file transition
towards it.
