ver_linux: Do not check for ver_linux pattern in version function
Checking whether output of commands matches the ver_linux pattern in the version function is original shell implementation legacy code. When the original implementation failed to locate a particular utility, it generated error output along the lines of: ver_linux:line number: command not found. The awk implementation, does not contain the name of the script within the body of the error message returned by the subshell when a given utility fails to be located. The error message returned is along the lines of: sh: name of utility: command not found Safeguarding against the ver_linux pattern being found in the output being parsed may thus be safely omitted.
