This patch fixes an issue when checking if a varflag
can be safely excluded.

BB_SIGNATURE_EXCLUDE_FLAGS lists variable flags that
can be safely excluded from checksum and dependency
data for keys in the datastore.

When bitbake checks if a varflag must be excluded it
checks if the varflag name is part of the string stored
in BB_SIGNATURE_EXCLUDE_FLAGS.

As an example, if the varflag 'filename' is in
BB_SIGNATURE_EXCLUDE_FLAGS, the varflag 'name'
will also be excluded because the check will return 'True'
when checking if the varflag is part of the string with
the varflags to exclude.

To fix this issue the string from BB_SIGNATURE_EXCLUDE_FLAGS
is converted to a list before checking if a varflag is part of it.
