i18n: use actual filename, in which function is defined, for hg.pot

Before this patch, source filename for msgid in hg.pot file becomes
incorrect, if a function is defined in file A, but detected in dict in
file B,

For example, almost all debug* commands are defined in
debugcommands.py, but hggettext detects them in "table" of
commands.py. Therefore, docstring fragments of debug* commands are
marked as "defined in commands.py" in hg.pot file.

This is serious problem for translation, because the cost to find out
original location of texts increases very much.
