classes/populate_sdk_ext: fix missing environment settings if running installer with sh
If you ran the extensible SDK installer file with sh (instead of bash),
then the additional call to buildtools environment setup, extension of
PATH to support running devtool, and setting of OE_SKIP_SDK_CHECK
weren't being added to the end of the script. This is because apparently
bash is happy to expand wildcards in the target of a redirection, but
bash running in POSIX sh mode won't (although it apparently does work on
the sh command line rather than within a script run as an argument to
sh). In any case using a wildcard here is a bit of a crutch which we
don't need, so replace it with the proper path to the environment setup
script.
