[PATCH 11/22] ver_linux: quota-tools, look for numerical input, not field number

[Alexander Kapshuk]

Rely on regex to find the version number, rather than rely on numerical input to be found in a particular input field.
Proposed implementation also eliminates the necessity to invoke 'grep' + 'awk'.
