svc: allow longer user and group names

Browse Source 
Service user and group names are stored in 16-byte buffers, limiting
them to 15 characters. This silently truncates longer names before
getpwnam() and getgrnam(), preventing services configured with valid
longer account names from starting.

Increase the buffers to match the existing maximum configuration
argument length.
