runtime: normalize sigprof traceback flags
Each gentraceback call uses a different set of flags. Combine these into
a common variable, only adjusted as necessary.
The effective changes here are:
* cgo traceback now has _TraceJumpStack. This is a no-op since it
already passes curg.
* libcall traceback now has _TraceJumpStack. This is a behavior change
and will allow following stack transitions if a libcall is performed on
g0.
* VDSO traceback drops _TraceTrap. vdsoPC is a return address, so
_TraceTrap was not necessary.
