pybootchartgui: be more tolerant when parsing proc_meminfo.log

waasdorp reports in bug #40 that we are raising an exception if
a line in proc_meminfo.log is not well formed.
He is right because we were trying to access matches of a regexp
that did not match.

That is obviously silly but it is also silly to stop processing
all the data if a line is wrong, even a line that we are not
interested in it. Instead ignore the line and skip the sample
if it is not valid.

Example of broken line:

While at it remove an unused variable
