Subject: [PATCH] Properly link in libudev once it is found

This fixes a subtle issue where libudev-rs assumes that the library files
are properly linked in which can result in a seemingly mysterious SIGSEGV
when using a musl-based libc distribution.

See [https://github.com/probe-rs/probe-rs/issues/2148](https://github.com/probe-rs/probe-rs/issues/2148)
for details.
