[OE-core] [PATCH] webkitgtk: Fix errors when api-documentation is enabled

[Richard Purdie]

This recipe hasn't built correctly since we removed "python" from HOSTTOOLS
when api-documentation is enabled.

Add in an extra symlink to "python" rather than trying to fix the multiple
scripts in webkit to refer to python3.

The autobuilder didn't detect this as wekbkit was excluded from the API docs
world build but that is changed now so this fixes build failures.
