Fix buggy bin/package environment behavior (#377)

Browse source 
Running 'bin/package environment' should only show what will happen
during the build process, but in it's current state the feature has
some bugs:

1. Errors can occur relating to the failed creation of files and a
   failed attempt to change the directory. Various errors from
   'bin/package environment make' and 'bin/package environment make
   CC=tcc':
   bin/package[5632]: cd: /home/johno/GitRepos/KornShell/ksh/arch/linux.i386-64/lib/package/gen: [No such file or directory]
   bin/package: line 5869: /home/johno/GitRepos/KornShell/ksh/arch/linux.i386-64/lib/package/gen/CC: cannot create [No such file or directory]
   bin/package: line 5869: /home/johno/GitRepos/KornShell/ksh/arch/linux.i386-64/lib/package/gen/CCFLAGS: cannot create [No such file or directory]
   bin/package: line 5869: /home/johno/GitRepos/KornShell/ksh/arch/linux.i386-64/lib/package/gen/CCLDFLAGS: cannot create [No such file or directory]
   bin/package: line 5869: /home/johno/GitRepos/KornShell/ksh/arch/linux.i386-64/lib/package/gen/LDFLAGS: cannot create [No such file or directory]
   bin/package: line 5869: /home/johno/GitRepos/KornShell/ksh/arch/linux.i386-64/lib/package/gen/KSH_RELFLAGS: cannot create [No such file or directory]
   bin/package[5888]: /home/johno/GitRepos/KornShell/ksh/arch/linux.i386-64/lib/package/gen/host: cannot create [No such file or directory]

2. The package script may in some scenarios create a temporary file
   at the root of the repository, such as 'pkg77213.c'.

bin/package, src/cmd/INIT/package.sh:
- Avoid creating files or changing the directory while the
  environment qualifier is on (this also affects the debug
  qualifier). Part of this fix is based on a patch from Marcin
  Cieślak[*], with other fixes applied for similar problems the
  environment qualifier had.
