service: add CAP_SETPCAP capability
The NetworkManager strongSwan and L2TP plugins fail due to not being able to drop capabilities:
dec 29 01:42:36 sylvester charon-nm[15164]: 00[LIB] dropping capabilities failed: Operation not permitted dec 29 01:42:36 sylvester charon-nm[15164]: 00[DMN] capability dropping failed - aborting charon-nm
dec 29 02:02:19 taz charon[2191488]: 00[LIB] dropping capabilities failed: Operation not permitted dec 29 02:02:19 taz charon[2191488]: 00[DMN] capability dropping failed - aborting charon
Fix this by adding CAP_SETPCAP to the CapabilityBoundingSet parameter of the systemd unit file.
