Subject: [PATCH] [build] fix `LOCAL_EXPORT_CFLAGS`  (#8453)

`LOCAL_EXPORT_CFLAGS` is exporting `OPENTHREAD_PROJECT_CFLAGS` which
contains quotes. This sometimes can cause compile errors due to
limitation of Android build system.

Also, `ot-cli` is repeating the flags in `LOCAL_CFLAGS`, which can
cause macro redefinition error. Since `ot-cli` depends on `ot-core`,
it already gets the flags from `LOCAL_EXPORT_CFLAGS`.
