[Chore](build) copy jeprof to output/be/bin (#58128)

This pull request updates the build script to change the source location
for copying BE binaries. Instead of copying specific BE shell scripts
from the old location, it now copies all files from the new BE output
directory, which helps ensure all necessary binaries are included.

Build script update:

* Changed the source path for copying BE binaries in `build.sh` from
`bin/*_be.sh` to `be/output/bin/*`, ensuring all BE binaries are copied
instead of just specific shell scripts.
