[LLDB] [test] Add a few missing cases of REQUIRES: python

lldb/lit/Commands/command-script-import.test

+# REQUIRES: python
 # RUN: echo 'b main' > %t.in
 # RUN: echo 'run' >> %t.in
 # RUN: echo 'command script import %S/Inputs/frame.py' >> %t.in
 
 # RUN: %clang -g -O0 %S/Inputs/main.c -o %t.out
 # RUN: %lldb -b -s %t.in -o 'script print("script: {}".format(lldb.frame))' %t.out | FileCheck %s
 
 # Make sure that we don't have access to lldb.frame from the Python script.
 # CHECK: frame.py: None
 
 # Make sure that we do have access to lldb.frame from the script command.
 # CHECK: script: frame #0

lldb/lit/Reproducer/TestSynchronous.test

+# REQUIRES: python
 # Ensure that replay happens in synchronous mode.
 
 # RUN: rm -rf %t.repro
 # RUN: %lldb -x -b --capture --capture-path %t.repro -o 'script lldb.debugger.SetAsync(True)' -o 'script lldb.debugger.GetAsync()' -o 'reproducer generate' | FileCheck %s --check-prefix CAPTURE
 # RUN: %lldb --replay %t.repro | FileCheck %s --check-prefix REPLAY
 
 # CAPTURE: script lldb.debugger.SetAsync(True)
 # CAPTURE-NEXT: script lldb.debugger.GetAsync()
 # CAPTURE-NEXT: True
 
 # REPLAY: script lldb.debugger.SetAsync(True)
 # REPLAY-NEXT: script lldb.debugger.GetAsync()
 # REPLAY-NEXT: False
