RF,BF: Adjust `Runtcl` to honour `$FSLDEVDIR`; fix bug in `update_fsl_package`

Paul McCarthyrequested to merge
mnt/runtcl into master
  • Fix a bug in update_fsl_package. Some noarch conda packages have separate releases for different platforms (e.g. if the package dependencies differ across platforms). These "noarch variant" packages will depend on a meta-package denoting the platform - one of __linux, __osx, or __win. The update_fsl_package was not taking this into account, so could select an incompatible variant for the running platform.
  • Adjust $FSLDIR/bin/Runtcl to run TCL entry points from $FSLDEVDIR/tcl/ if they exist, and fall back to the official versions in $FSLDIR/tcl/.
