[PATCH proxmox-perl-rs v1] make: fix library path detection for tests

["Max R. Carrara" <m.carrara@proxmox.com>]

Export a new variable containing the absolute path to the current
Rust target's directory and pass it to PERL5LIB [0] in the tests'
Makefile.

This allows the bootstrap machinery in Proxmox::Lib::PVE to find the
compiled .so file when testing and building.

Since it's not needed anymore, remove the `sed` workaround in the
`all` target.
