By reversing the logic and adding a `REMOVE_SYMBOLS` environment
variable that, when set, will remove symbols.
This has been requested to re-enable Dynatrace support, which
requires symbols are intact.
Sadly this increases the size (on my mac) from 192,609,682 bytes
to 236,696,722 bytes (+23% increase).
I confirmed that this adds symbols back, and that `dlv` will load
the Vault binary.
