Use env pwd instead of pwd in crunchgen.c

Browse Source 
In r364166 I changed /bin/pwd to pwd, but pwd can be shell builtin that
may not correctly return a real path. To ensure that all symlinks are
resolved use `env pwd -P` instead (the -P flag is part of POSIX so
should be supported everywhere).
