[PATCH] BBHandler: Don't classify shell functions that names start with "python*" as python function

[Tomasz Dziendzielski]

If shell function name starts with 'python' or 'fakeroot' parser wrongly
assumes it's python/fakeroot function.

[YOCTO #14204]

Use regex lookahead assertions to check if 'python' expression is
followed by whitespace or '(' and if 'fakeroot' is followed by
whitespace.
