[Buildroot] [PATCH] support/scripts/pkg-stats: add tilde '~' expansion for pathes

[Heiko Thiery <heiko.thiery@gmail.com>]

The script arguments 'nvd-path', 'json' and 'html' currently does not
allow to have '~' in path for user home directory. With this patch
this '~' is expanded to the real user home directory.
