fix(exec/redirections): did not correctly restore fds when executing builtins

Browse source 
This caused redirections to keep stdout redirected to the outfile, which caused
problems with displaying the prmpt.

The shell hangs, but exits with C-d

Builtins affected:
echo hi > outfile
pwd > outfile
env > outfile
