Fix NNAPI mlts test script to read output from /storage/emulated/0 instead
of /sdcard
The test Java code writes to Environment.getExternalStorageDirectory()
while the script has the path hardcoded.
Tested on several devices (including non-rooted) that they all return
the new path and it has read/write access.

Test: Ran script on several devices:
On Pixel 6 (non-rooted), Pixel 7 (rooted), Vivo x80 (non-rooted):
test/mlts/benchmark$ ./build_and_run_benchmark.sh -n arm -f arm-armnn-sl -x -s
