[testsuite] Replace fragile 'scan-assembler' with 'scan-offload-rtl' in 'libgomp.oacc-c-c++-common/pr85381*.c'

Browse Source 
These test cases use directives similar to:

    /* { dg-additional-options "-save-temps" } */

    /* { dg-final { scan-assembler-times "bar.sync" 2 } } */

This expects to scan the PTX offloading compilation assembler code (not host
code!), expecting that nvptx offloading code assembly is produced after the
host code, and thus overwrites the latter file.  (Yes, that's certainly
ugly/fragile...)

..., and this broke with recent commit 1dedc12d18
"revamp dump and aux output names" plus fix-up commit commit
efc16503ca "handle dumpbase in offloading, adjust
testsuite" (short summary: file names changed), so let's finally make that
robust.
