make escriptize reproducible with erlang 27.1

[delitrem]

Hi, Fred.

I've already submitted fix related to reproducible escripts generation. Here is minor additional change to make it work with newer Erlang 27.1.

Before patch:

% for a in $(seq 1 3); do ./bootstrap 2>&1 >/dev/null; md5sum rebar3; done
4af061db0dffb624cbcc4f791bec4811  rebar3
934a4bb8fc774c651fc88ecd2c906f9d  rebar3
da14315045711bda5bc9f7c99175e715  rebar3

After patch:

% for a in $(seq 1 3); do ./bootstrap 2>&1 >/dev/null; md5sum rebar3; done
98ec28baced972e9f59b1ff4e84cbc07  rebar3
98ec28baced972e9f59b1ff4e84cbc07  rebar3

Thank you!
