updateBoost.sh doesn't work on macOS because 'dirname' doesn't have '--version' option #73

@thewtex KWSys's updateBoost.sh script doesn't work on macOS because the macOS 'dirname' doesn't have a '--version' option.

Perhaps there is a different way to check that dirname exists?

If I remove that 'validate' section of code, the script then works.

@seanm A better option may be the type built-in from bash:

On my Mac:

leprechaun:Desktop sean$ type dirname
dirname is /usr/bin/dirname

Fixes issue Kitware#73. macOS dirname does not have a `--version` option, which was making the script fail on macOS. This technique should be POSIX compliant and more crossplatform.
