rev-parse: clear --exclude list after 'git rev-parse --all'

Commit [1] added the --exclude option to revision.c.  The --all,
--branches, --tags, --remotes, and --glob options clear the exclude
list.  Shortly therafter, commit [2] added the same to 'git rev-parse',
but without clearing the exclude list for the --all option.

[2] 9dc01bf ("rev-parse: introduce --exclude=<glob> to tame wildcards", 2013-11-01)
