[PATCH] scripts/gen-btf.sh: fix shebang for NixOS

[Gary Guo]

From: Gary Guo <gary@xxxxxxxxxxx>

NixOS only puts /usr/bin/env and /bin/sh at the standard location as
required by POSIX, but not other shells. Other program that kernel build
depends on is supplied via PATH, so shebang needs to use /usr/bin/env to
find them.

This has been done to a few other scripts already, e.g.
gen_test_kallsyms.sh or decode_stacktrace.sh.

Fixes: 522397d05e7d ("resolve_btfids: Change in-place update with raw binary output")
