profile: set python 3.6 single target for cross builds

Now that `cross-{x86_64,aarch64}-cros-linux-gnu/gdb` was updated to 9.1,
it needs exactly one of `python_single_target_python3_6` and
`python_single_target_python3_7`. Since python 3.7 is not available yet,
we need to enable 3.6 and disable 3.7, for the SDK profile.

Without the fix, toolchain builds will fail like that:

```
!!! The ebuild selected to satisfy "cross-aarch64-cros-linux-gnu/gdb"
has unmet requirements.
- cross-aarch64-cros-linux-gnu/gdb-9.1-r1::x-crossdev USE="client nls python server -lzma -multitarget -source-highlight -test -vanilla -xml -xxhash"
  PYTHON_SINGLE_TARGET="-python3_6 (-python3_7)" PYTHON_TARGETS="python3_6 (-python3_7)"

  The following REQUIRED_USE flag constraints are unsatisfied:
    python? ( exactly-one-of ( python_single_target_python3_6 python_single_target_python3_7 ) )

  The above constraints are a subset of the following complete expression:
    python? ( exactly-one-of ( python_single_target_python3_6 python_single_target_python3_7 )
              python_single_target_python3_6? ( python_targets_python3_6)
              python_single_target_python3_7? ( python_targets_python3_7 ) ) any-of ( client server )
```
