GenerateExportHeader: Fix add_compiler_export_flags regression

Browse Source 
The mechanical conversion in commit 5d0d980d (Use string(APPEND) in
Modules, 2016-07-28) accidentally introduced use of

  string(APPEND ... PARENT_SCOPE)

Split that into the string(APPEND) and set(PARENT_SCOPE) pieces.
