configure.ac: change regex for sed version
Change regex for sed version in configure.ac.
This regex will match only on the first line and doesn't
look for a 'version' pattern which is not available in
sed version 4.2.2.
The new regex will match in the first line of 'sed --version' in a pattern
which starts with random character sequence(or zero) followed by whitespace
character and several digits of pattern x.x....x which x is a number.
This pattern will be save in the SED_VERSION variable.
