[PATCH 03/22] ver_linux: binutils, fix inaccurate output

[Alexander Kapshuk]

Current implementation output on Gentoo Linux:
binutils               2.25.1
1.1
2.25.1

Proposed implementation:
Binutils		2.25.1

Tested on:
Gentoo Linux
Debian 6.0.10
Oracle Linux Server release 7.1

Rely on regex to find the version number.
