Panda: Don't try to resolve depencies

Without this, Panda tries to access the network to resolve the deps for
some modules (16 out of 32 at the moment), leading to them getting
skipped when Rakudo is installed without a network connection.

There's no need to resolve dependencies anyway since modules/MODULES.txt
takes care of listing modules in the correct order.

Here's what you otherwise get without a network connection:

```
==> Installing NativeHelpers::Blob from a local directory
'modules/NativeHelpers-Blob'
==> Fetching NativeHelpers::Blob
==> Building NativeHelpers::Blob
==> Testing NativeHelpers::Blob
==> Installing NativeHelpers::Blob
==> Successfully installed NativeHelpers::Blob
==> Installing DBIish from a local directory 'modules/DBIish'
Could not download module metadata: Failed to connect: network is
unreachable.
Falling back to the curl command.
curl: (7) couldn't connect to host
curl failed: The spawned process exited unsuccessfully (exit code: 7).
Falling back to the wget command.
wget failed as well: The spawned process exited unsuccessfully (exit
code: -1). Sorry, have to give up.
