chore(deps): update build-emacs-for-macos to 0.6.36

By default the build script will enable native-comp if it detects it in
the source tree. This caused recently nightly builds of master to be
built without native-comp due to recent changes in Emacs' configure
script which broke native-comp detection. More details here:

https://github.com/jimeh/build-emacs-for-macos/issues/76

Hence we explicitly enable native-comp now for the nightly master and
emacs-28 builds, which will cause the build script to fail if it cannot
detect native-comp support in the source tree.

Any failure to detect native-comp in master and emacs-28 branches would
at this point be due to a bug/issue with the build script, rather than
Emacs' source tree.
