[NaCl SDK] Silence objdump warning when building w/ Chrome dev/beta.

[NaCl SDK] Silence objdump warning when building w/ Chrome dev/beta.

objdump was failing when running beta or dev branch of Chrome, because the
filename is now google-chrome-beta or google-chrome-dev.

The code in getos.py was only checking for google-chrome.

Can we also check that it exists and is executable?
