Inkwell cannot be built on MacOS

[BigBadE]

Describe the Bug
values/mod.rs line 228 expects section to be a &str, but a conditional compilation block uses format! to modify section, making it a String. This was introduced by #398.

To Reproduce
Build on MacOS

Expected Behavior
Build success

LLVM Version (please complete the following information):

• LLVM Version: [e.g. 6.0]
  18.0

Additional Context
