package/mfgtools: bump to 0.02

Bump mfgtools to include the fix [1] for the C++ build issue reported
by the autobuilders.

This bump include only 4 small commits fixing memory leak and this
build issue.

Remove CPOL.htm (removed upstream) from MFGTOOLS_LICENSE_FILES but CPOL
license is still valid.
Add the README.txt file to MFGTOOLS_LICENSE_FILES since it contains
licensing informations:

Licenses:
- CPOL: MfgToolLib/XmlLite.CPP and XmlLite.h
- BSD: Others.

Add license file hash.
