tools: moveconfig: support wildcards in --defconfigs file

Supporting shell-style wildcards for the --defconfigs option will be
useful to run the moveconfig tool against a specific platform.  For
example, "uniphier*" in the file passed by --defconfigs option will
be expanded to defconfig files that start with "uniphier".  This is
easier than listing out all defconfig files you are interested in.
