Plugin apache_memory: properly quote patterns and simplify calculation

• patterns with whitespace caused errors
• the number of processes could change between the steps for
  counting and averaging
• handle "no match" properly (returning "U" - unknown - instead of an
  error)
• avoid calculation based on unsafe "eval"

    exit 0
