Update devel_check_plugins.asciidoc

While following the tutorial, I noticed an error in the example code. To make it work, I removed the extra space from the code example.

Hi pungme, thanks for finding the error! I found another one in the same line (prompt root@linux should be OMD[mysite]). So I corrected it manually both in English and German. Thomas
