old varnishreload

Description:

The package is using upstream scripts but is a bit behind, so varnishreload suffers from a bug that has since been fixed: https://github.com/varnishcache/pkg-varnish-cache/issues/177

The commit that fixed it: https://github.com/varnishcache/pkg-varnish-cache/commit/22fc900bb97597e14747bd5ceacc22f0c1b3c6c6

Additional info:

• package version(s): 7.6.0-1
• link to upstream bug report, if any: https://github.com/varnishcache/pkg-varnish-cache/issues/177

Steps to reproduce:

run varnishreload -h, you'll see the warning about the unbound variable and the missing example near the bottom
