Update verify_release.sh to work with 30.0.0 via workaround

[alamb]

Which issue does this PR close?

closes #3410

Rationale for this change

parquet now has an optional dependence on object_store but object_store is not part of the tarball and thus the verify script fails

What changes are included in this PR?

A hack to the verify_release script to fix the verification and remove the path marker in the object store dependency declaration

@tustvold has noted that rather than changing the verify script the actual tarball should probably be fixed (aka so that it does not have references to path. I will write up a follow on ticket for this issue

Are there any user-facing changes?

No

[tustvold]

I'm not a fan of this, but if it unblocks things we can fix it properly later

[alamb]

I tested that this script can successfully verify 30.0.0 rc 1
