[klibc] dash: Fix "pwd -P" breakage due to getcwd(0, 0) usageklibc-1.4.32
The getpwd() function in dash assumed than getcwd(0, 0) will
allocate the buffer dynamically using malloc(); however, this
glibc extension is not implemented by klibc. Make getpwd() use a
temporary buffer and invoke savestr() itself instead of relying on
a nonstandard extension.
