electron-bin: don't wrap inside libexec

This change helps bring electron-bin to a similar structure as the
source builds of electron.
The primary motivation of this change was to ensure that the `electron`
binary inside `libexec/electron` is an actual binary and not a wrapper.
This way `electron-fuses` will not complain about not being able to
find the necessary sentinel strings inside the binary.
