[OE-core] [PATCH 1/1] telepathy-mission-control: do_compile failed (race issue)

[Robert Yang]

There might be an error when parallel build:

[snip]
Traceback (most recent call last):
  File "/path/to/tools/glib-gtypes-generator.py", line 304, in <module>
    GTypesGenerator(dom, argv[1], argv[2])()
  File "/path/to/tools/glib-gtypes-generator.py", line 295, in __call__
    file_set_contents(self.output + '.h', ''.join(self.header))
  File "/path/to/tools/libtpcodegen.py", line 42, in file_set_contents
    os.rename(filename + '.tmp', filename)
OSError: [Errno 2] No such file or directory
[snip]

This is a race issue, the _gen/gtypes.h and _gen/gtypes-body.h may
write(remove/rename) _gen/gtypes.tmp at the same time, then there would
be the error.

There was a similar bug in telepathy-glib which was already fixed, we use the
similar patch to fix it here.
