[Buildroot] [git commit] support/scripts/mkusers: fix UID/GID confusion

[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=ebbcf5a0a752519efffeba432f347b49950b1f16
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Commit 41ea61d59c3e (support/scripts/mkusers: allow option for system
uid/gid) confused GID and UID variables: the GID limits were used to
create UIDs.

Fix that.

Note that this fixes a shellcheck error; although there are many more
shellcheck errors, these fixes are semantically a bug that need to be
fixed separately from the coding style issues reported by shellcheck.
