procfs 0.17.0 requires Rust 1.70.0

[tyilo]

According to Cargo.toml procfs supports Rust 1.48. However it fails to build on versions below 1.70.0.

We are currently using procfs with Rust 1.67.1, where we get the following error when compiling:

Either the MSRV should be bumped or procfs-core should support Rust 1.48.

Sorry about that. Cargo.toml got out-of-date somewhere along the way. It should be updated to match the actual MSRV
