[OE-core] [=OE-core][PATCH] populate_sdk_base.bbclass: fix broken variables

[Ioan-Adrian Ratiu]

This function never worked because the SDK_OUTPUT and SDKPATH vars are
written bash-style in a python function. The only reason it never failed
a build is because the function bails out the start because of the flag
CHECK_SDK_SYSROOTS.

And I guess nobody tested with CHECK_SDK_SYSROOTS enabled until now.
