remove unneeded getenv declaration

*Not tested with gcc 15*
I duplicated the issue with both gcc 13 with -std=gnu2x as well as clang 18 with -std=gnu23.
The source in question declares char* getenv() which is already defined in included headers.
Removing this declaration, it compiles with gcc 13 and clang 18 with and without the -std flags.
