[Buildroot] [git commit branch/2023.02.x] package/linux-tools/S10hyperv: fix shellcheck warnings

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=9581a99263cf866f8cfd60dec4ad299f7edc5c4c
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2023.02.x

When running "make check-package" on a system with shellcheck 0.9.0,
the command fails with output:

    make check-package
    package/linux-tools/S10hyperv:0: run 'shellcheck' and fix the warnings
    ...
    2 warnings generated

This commit fixes the warnings reported by the command:

    shellcheck package/linux-tools/S10hyperv

This commit also fixes the four-space indent by a single tab on the
changed lines. Since this fixes the indentation warnings of
check-package, the Indent exclusion in .checkpackageignore is also
removed.

Fixes:
