change: Replace profile overwrites to Workspace Cargo.toml (#95)

Since profile info specified inside workspace members `Cargo.toml`'s
is ignored by Cargo, this replaces the place to specify these details
for the workspace-level `Cargo.toml`.

NOTE that `panic` and `rpath` aren't supported with the Overwritting
feature. Therefore, the only required thing (if considered necessary) is
to create a new profile which also enables these things.

Resolves: #93
