    libsframe: testsuite: fix PR libsframe/33140
    
    Commit 0d4d5a2633f missed some necessary adjustments to the testcase
    after rebase.  SFrame FDE function start address data is now an offset
    in PCREL encoding; reflect with a new flag SFRAME_F_FDE_START_ADDR_PCREL
    in the header.
    
    Adjust the newly added testcase.

            * libsframe.find/plt-findfre-2.c: Adjust for the new FDE func
            start addr encoding.
