Make the reldbg profile default for SDK builds again

[stefanceriu]

Following matrix-org/matrix-rust-sdk#2765 we need to switch back to reldbg which not contains debug symbols but also doesn't crash

Revert "Debug is no longer crashing as of matrix-rust-sdk/pull/2595time to make it the default again so that debugging works properly"

This reverts commit eb9c69c.
