chore: remove duplicate and un-needed files from dist zips (#14882)

* chore: remove duplicate and un-needed files from dist zips

* Strip chromedriver binaries

Also, fix path for files to skip

* Don't strip mksnapshot for now

Mksnapshot needs special handling for arm/arm64 because there is both an x86 and arm/arm64 binary in those cases.
