ftp(1): anonymous login and .netrc

[Anton Lindqvist]

I'm running a script as root which drops privileges while fetching files
using ftp(1) with anonymous login enabled:

# doas -u unpriv ftp -a URL

... and was surprised to see the following error:

ftp: /root/.netrc: Permission denied

I'm not sure if the .netrc file should be considered when anonymous
login is enabled. If not, here's a patch:
