toolchain-shar-relocate: don't assume last state of env_setup_script is good

In the case where many environment-setup-* files exist, the incorrect
filename might be lastly set in env_setup_script, which leads to
incorrect behaviour for the initialization of native_sysroot.

The scenario I had was that our custom meta-toolchain-*.bb, which
inherits populate_sdk, defined another environment-setup-* file to dump
variable information for qt-creator. The file is named like so in order
for the sdk shell script to pick it up and fix the SDK paths in the
file. Since it (coincidentally) alphabetically comes after ...-core2, it
was last set in env_setup_script and the grep OECORE_NATIVE_SYSROOT
would simply be blank. The apparent symptom was "...relocate_sdk.py:
Argument list too long" since the find command would not be searching in
the right path.
