misc/amanda-server: Mark jobs unsafe

I'm not sure why I've never seen this before, but I've recently seen both
amanda-client and amanda-server fail due to parallel building errors
this week on separate runs.  Limit building to 1 CPU and remove "The"
from the start of the COMMENT while here.
Upgrade to version 1.702.
Upgrade to version 4.11.
- Update to 2.8 . [1]
- Change ac_cv_path_AVCONV_PATH from no to the empty string so that
  dvdstyler actually calls ffmpeg not avconv.

Disable function importing from the environment by default.  This can be
enabled by using --import-functions or enabling the IMPORTFUNCTIONS option.

This removes the risk of further parser bugs leading to code execution, as
well as the risk to setuid scripts and poorly written applications that
do not cleanse their environment [1][2].

Also note that there is an unofficial 4.3.26 floating around that has not yet
been officially released.  r369261 covers the change in 4.3.26.
