Werk #11874: Linux agent: Fix execution of cached plugins (2.0.0b4 regression)

The 2.0.0b4 release introduced a regression in the Linux agent which broke the execution of cached agent plugins (which also includes the agent updater for example). The plugins that are placed below /usr/lib/check_mk_agent/plugins/[seconds] were not executed at all in 2.0.0b4.

Possible workarounds:

• Move the plugin to the /usr/lib/check_mk_agent/plugins directory to execute it every check cycle
• Use an agent of previous 2.0.0 releases
• Use the agent from a daily build 2021-01-16 or newer
