[pbs-devel] [PATCH proxmox-backup] build: use cargo wrapper when building package

[Fabian Grünbichler]

else we don't pick up the options set by the wrapper, which include generation
of debug symbols. until rustc 1.77, this was not needed because compiled
binaries always included a non-stripped libstd. now, without this change, the
binaries built with `cargo build --release` have no debug symbols at all
trigger a warning. fix this and include debug symbols when building a package,
like was originally intended for release package builds.

no obvious fallout I could find, but more eyes probably don't hurt. 1.77 is not
in the repository yet, I'll upload it tomorrow..
