[OE-core] [PATCH] package_deb: Remove version from Provides Field

[Ricardo Ribalda Delgado]

According to Debian Policy Manual. Chapter 7.1

All of the fields except for Provides may restrict their applicability
to particular versions of each named package. This is done in
parentheses after each individual package name; the parentheses should
contain a relation from the list below followed by a version number, in
the format described in Version, Section 5.6.12.

This Fixes the following warning:

root at qt5022:~# apt-get update

...

Reading package lists... Done
W: Ignoring Provides line with DepCompareOp for package
pkgconfig__pkg-config__
W: You may want to run apt-get update to correct these problems
