preload tracer sets errno

**Description of the issue**
The library that gets preloaded by the `preload_tracer` sets the `errno` to `EINVAL`

This seems to be a similar issue to https://github.com/rizsotto/Bear/issues/469 and prevents the Linux kernel from being able to compile fully due to the use of errno here:

Read the preload_tracer implementation and the referenced scripts/kallsyms.c line 134, then reproduce the Linux kernel build failure shown in the report. Trace where the preloaded library changes errno and verify completion by confirming that the kernel build no longer reports “read_symbol: Invalid argument”.
