Author: Charles-Francois Natali <cf.nat...@gmail.com>

Fixed agent crash when kernel supports unknown capabilities.
When capabilities are enabled, the capabilities initialisation code
would check that /proc/sys/kernel/cap_last_cap is less than
MAX_CAPABILITY, i.e. that the kernel doesn't support any capability the
code doesn't expect. However the error message attempted to format
cap_last_cap value as a Capability enum, which would crash.
Part of fix for #10203.
