[kernel] remove trailing directory globs in forbidden paths

Since the forbidden path test now uses an exact match the trailing
globs ("/some/directory/path/to/exclude/*") used to exclude trace
related directories from collection lead to a failure to properly
blacklist these files:

The glob is expanded, for e.g.:

  "/sys/kernel/debug/tracing/per_cpu/*"

Expands to unclude a 'cpuN' sub-directory for each CPU present on
the machine. These expanded paths are then added to the forbidden
paths list for the plugin:

  /sys/kernel/debug/tracing/per_cpu/cpu0
  /sys/kernel/debug/tracing/per_cpu/cpu1
  ...

When an attempt is made to collect the entire "per_cpu" directory
a check is made for the full "/sys/kernel/debug/tracing/per_cpu"
path against each entry in the forbidden paths list. Since this is
a prefix of the actual paths stored no match is returned and the
collection is permitted.

Remove the trailing globs from these directory paths and prevent
any collection of the directories they reference by the plugin.
