Subject: [PATCH 01/10] [Plugin] remove invalid {strip/join}_sysroot()

Do not strip the sysroot path prefix when calling _do_copy_path()

for a symlink target and do not add the sysroot prefix when

testing for a forbidden path.

Subject: [PATCH 02/10] [Plugin] fix destination paths in _do_copy_path()

The path used to copy special device nodes and directories in

_do_copy_path() should be the destination path in the archive

(without sysroot prefix), and not the source path in the host

file system that includes this prefix.

Subject: [PATCH 03/10] [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.

Rather than call just Plugin.setup() and Plugin._do_copy_path(),

add an add_copy_spec() call to the mock plugin setup() method,

and invoke copying by calling the Plugin.collect() method.
