Subject: [PATCH] scripts/gdb: Add automatic path expansion when loading modules

Python doesn't do automatic expansion of paths. In case one passes
path of the from ~/foo/bar the gdb scripts won't automatically expand
that and as a result the symbols files won't be loaded. Fix this
by explicitly expanding all paths which begin with "~"
