Adhemerval Zanella 6e05978f0c mips: Fix bracktrace result for signal frames 
MIPS fallback code handle a frame where its FDE can not be obtained
(for instance a signal frame) by reading the kernel allocated signal frame
and adding '2' to the value of 'sc_pc' [1].  The added value is used to
recognize an end of an EH region on mips16 [2].

The fix adjust the obtained signal frame value and remove the libgcc added
value by checking if the previous frame is a signal frame one.

Checked with backtrace and tst-sigcontext-get_pc tests on mips-linux-gnu
and mips64-linux-gnu.
