init.sh: return from child in set_env instead

Browse Source 
This is earlier than the current check, thus preventing
the initialisation of a git repository and/or the recreation
of xbmktmp and xbmklocal by erroneous parent executions of lbmk
while another parent is running - the latter of which could have
caused a massively unpredictable build failure, so this is also
a pre-emptive bug fix, fixing all kinds of weird bugs.
