[pbs-devel] [PATCH proxmox-backup] build: include pxar in static binary compilation and package

[Christian Ebner]

The debian package providing the dynamically linked version of the
proxmox-backup-client is packaged together with the pxar executable.

To be in line and for user convenience, include a statically linked
version of pxar to the static package as well.

Renames STATIC_BIN env variable to STATIC_BINS to reflect that this
now covers multiple binaries and store rustc flags in its own
variable so they can be reused since `cargo rustc` does not allow
invocations with multiple `--package` arguments at once.
