yum: Disable package-note-file to remove unnecessary linker flag (#877)

The user can refer the Ruby configure results through
`RbConfig::CONFIG`.
`RbConfig::CONFIG` is mainly used when installing gems which has C
extension.

If flags remain that use linker scripts that do not exist in the user's
environment,
it causes errors when user install the gem.

When creating a package using `fluent-package.spec.in`, the environment
variable `LDFLAGS` was automatically set as follows.

```
LDFLAGS='-Wl,-z,relro -Wl,--as-needed  -Wl,-z,now -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1    -Wl,--build-id=sha1 -Wl,-dT,/root/rpmbuild/BUILD/fluent-package-6.0.0/.package_note-fluent-package-6.0.0-1.amzn2023.x86_64.ld'
```

Ruby's `configure` refers to the environment variable `LDFLAGS`,
and it expands into `RbConfig::CONFIG`.
