net-analyzer/fem-nagios-plugins: Update dependencies, refactor
This is a refactoring of the current 2.1.0 ebuild, since the old ebuild uses way too many USE flags and had huge amounts of boilerplate code. This commit introduces a PLUGIN_FLAG_MAP for plugins that should be installed conditionally, allowing an easy mapping of USE flags to the corresponding plugin names. Other plugins are in a PLUGIN_LIST so that the installation only has to append the PLUGIN_LIST with the items from PLUGIN_FLAG_MAP depending on whether the corresponding USE flags are set and afterwards installing everythin in a for loop. This reduces boilerplate code for checking each USE flag drastically and makes the build easier to read.
All USE flags for plugins which don't introduces additional dependencies are dropped. These plugins are now installed unconditionally, thus reducing the amount of USE flags to be configured.
As all dependencies are only required at runtime, DEPEND is removed and only RDEPEND is used. Furtheremore, a missing dependency for the hddtemp plugin is added.
