libsystemd/253.*: Fix cross-compilation

[jwillikers]

Specify library name and version: libsystemd/253.*

Bump versions of pkgconf and Meson.
Add a patch to ensure that necessary compiler flags are passed through when the build system is invoking the compiler to generate files.
Without the proper compiler flags when cross-compiling, the system include directories and such are used which causes problems.
The patch has been applied upstream in systemd/systemd#29538.

• I've read the contributing guidelines.
• I've used a recent Conan client version close to the currently deployed.
• I've tried at least one configuration locally with the conan-center hook activated.

It's great to see that you yourself fixed it upstream 🫶

Thanks! 😊 It would feel way cooler if I wasn't simply unreverting a single-line change from 5 years ago that ended up fixing the problem after updates to Meson 4 years ago, but that seems to be the way of Open Source at times. I've yet to grasp why no one had fixed this in the past 4 years, though. 🤔
