Allow uname calls in download mode + Fix handling of files without RPATH (#37129)
... and don't fetch patchelf unless we actually need it. For example
cmake helper ports have no need to fetch patchelf.

In https://github.com/microsoft/vcpkg/pull/36056 , things were changed
to unconditionally patchelf when targeting Linux. Unfortunately that
broke --only-downloads a lot of the time. This fixes that.

Also contains @Osyotr 's fixes from
https://github.com/microsoft/vcpkg/pull/37190 to coalesce world rebuilds
a bit, so repeating comments from there:

Fixes https://github.com/microsoft/vcpkg/issues/37183
