    [gdb/testsuite] Fix regexp for reg value in jit-reader.exp
    
    On openSUSE Leap 15.1 (as well as on Fedora-x86_64-m64 buildbot) I see:
    ...
    FAIL: gdb.base/jit-reader.exp: with jit-reader: after mangling: current frame: info registers
    ...
    
    The problem is that r10 is printed signed:
    ...
    r10            0xffffffffffffffb0  -80^M
    ...
    but the regexp expects a signed value:
    ...
                "r10            $hex +$decimal" \
    ...
    
    Fix this by allowing signed values.
    
    Tested on x86_64-linux.
