[OE-core] In dash there is no "echo -e"

[Andrei Gherzan]

Hello,

oe-core / yocto removed the prerequisite to have sh pointing to bash. This
means that echo -e in dash will actually print "-e" and interpret
backslashes by default.

Now, in oe-core / yocto there are a couple of occurrences of "echo -e".
Generally these are scripts with bash shebangs - so no problem here. But
there are 4 classes which use this:

buildhistory.bbclass
package_rpm.bbclass
package_deb.bbclass
package_ipk.bbclass


My solution would be to replace echo with print in these cases.
