authpf(8) read_config() should chop off trailing white space

Browse Source 
if administrator mistakenly types into configuration file

anchor=authpf_test

where 'authpf_test' is followed by white space, the authpf(8)
is going to use anchor 'authpf_test ' instead of the 'authpf_test'
which is defined in pf.conf(5) as 'anchor authpf_test/*'
