[Buildroot] [git commit] graph-depends: avoid use of global var 'rule' in get_depends

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=bd8b531d24431141a919daf6c50cca7de8547023
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Function get_depends was recently changed to support both normal
dependencies as reverse dependencies, via a global variable 'rule' that
equals 'show-depends' or 'show-rdepends'.

As a subsequent function will extract this function get_depends to a
separate file, the use of globals is problematic.

Instead, pass the global as an argument.
