Use a build/ directory in the build directory, not in the source
directory, since the source directory may be read-only and must not
be modified.

I tested again with a fresh read-only source directory and I'm able to build Python and run tests with this change (whereas running tests fails without this change).

Hum, it seems like the variable is not available on Windows:

C:\projects\cpython>"C:\projects\cpython\PCbuild\win32\python.exe"  -u -Wd -E -bb -m test  -uall -rwW --slowest --timeout 1200 -j0 
Traceback (most recent call last):
  ...
  File "C:\projects\cpython\lib\test\libregrtest\main.py", line 31, in <module>
    TEMPDIR = os.path.join(sysconfig.get_config_var('abs_builddir'), 'build')
  File "C:\projects\cpython\lib\ntpath.py", line 75, in join
    path = os.fspath(path)
TypeError: expected str, bytes or os.PathLike object, not NoneType

Use a build/ directory in the build directory, not in the source
directory, since the source directory may be read-only and must not
be modified.

Fallback on the source directory if the build directory is not
available (missing "abs_builddir" sysconfig variable).

I checked manually that it fixes the issue of read-only source tree: I'm now able to run tests from the build directory.
