Bug#1086569: expect: Remove /usr/bin/ftp-rfc (and likely expect_ftp-rfc) from install

[Daniel Lange]

Package: expect
Version: 5.45.4-2+b1
Severity: minor

Dear Sergei,
ftp-rfc uses ftp.uu.net which is defunct since the 2000s.

Please remove this expect sample code from the install set (/usr/bin) as 
well.

Kind regards,
Daniel
