Musl supplies no argument to constructors in .init section, thus it's
hard to retrieve environment variables without libc functions. Let's
depend on "environ" variable for now, which is relatively fine in
libdrpreload.so.
This fixes tests requiring late injection on musl, including common.fib,
common.nativeexec and common.nativeexec_{exe,bindnow}*.
