[strongSwan] How to flush certificate cache

[Martin Willi]

Tobias just told me that he did some changes to the certificate
handling, newly added certificates should get preferred. This does not
completely fix the issue, but might work for you. After doing "ipsec
reload", you'll have to invoke "ipsec purgex509" to flush the internal
certificate cash.

Patching 4.5.0 is a little difficult, as a lot of changes are involved.
You might try a snapshot [1] from the current HEAD.
