fix: issue on building with Xcode 16.0+

[zacky1972]

Hi,

I tested the building script taught by @wojtekmach

#41 (comment)

$ gh repo clone erlef/otp_builds
$ cd otp_builds
$ sh scripts/build_otp_macos.bash OTP-27.1.2
$ tmp/otp_builds/otp-OTP-27.1.2-openssl-3.1.6-wxwidgets-3.2.6/bin/erl
Erlang/OTP 27 [erts-15.1.2] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [jit]

Eshell V15.1.2 (press Ctrl+G to abort, type help(). for help)

Unfortunately, I got the following error:

In file included from sys/unix/erl_unix_sys.h:65:
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/unistd.h:525:10: fatal error: cannot open file 'aarch64-apple-darwin/opt/jit/_ctermid.h': Too many open files

      |          ^

make[3]: *** [opt] Error 2
make[2]: *** [opt] Error 2

Fortunately, I know how to fix this issue:

asdf-vm/asdf-erlang#319

ulimit -n 65536

This PR patches this on scripts/build_otp_macos.bash.

Thank you.

Thank you. The change seems reasonable. I'll approve the CI run, but let @wojtekmach review it later.
