build: Allow ipsec-mb plugin to build with libipsec_mb 0.55
The 0.55 version of libipsec_mb does not support the chacha functions
used in the plugin.
The missing symobls are:
ipsecmb_ops_chacha_poly
ipsecmb_ops_chacha_poly_chained
IMB_CIPHER_DIRECTION
Check for ipsecmb_ops_chacha_poly() and conditionalise the chacha code
in the plugin on this.
ipsec_mb 0.55 is the version currently found in Debian Stable (bullseye)
Type: make
