python-tools.sh, py-mod.mk: Use --symbol-filter

Letting python-tools.sh rewrite symbols is more robust than rewriting an entire __init__.py with PY_INIT_FILTER in the including Makefile. The latter can break in non-obvious ways if python-tools.sh changes __init__.py's format.
Make python-tools.sh support --symbol-filter to remedy that. The option takes an sed script which should expect a string of two non-whitespace tokens: The module from which the symbol is imported, and the name of the symbol in that module. It's output will then be used as the symbol to be exported from __init__.py.
Also, support the PY_SYMBOL_FILTER variable in py-mod.mk. If it's defined, it is used for --symbol-filter.
