added sqlite3 py libs

[msterin]

sqlite3 .so binaries and .py code are added to repo (32bit linux build) , and are added to VIB.
They are added to the python load path in vmdk_ops for python2

Fixes #646

Test: manual runs of 'make test-esx' on ESX 6.0 Update1 and ESX 6.0 Update 3

Background:

• sqlite3 py support was added by vsanhealth in ESX 6.0 Update 2 and later.
• In ESX 6.5, sqlite3 libs are native to Python3.
• However, on Python 2 on ESX 6.0 and 6.0 Update1, there are missing and need to be added to the path
• sqlite3 libs are based on https://pypi.python.org/pypi/pysqlite and are part of Python PIP packages.
• SInce ESX does not have PIP installed , we are dropping files manually for our exclusive usage
