Don't encode the current timestamp.

This affects the output of `perl -V`, specifically the message "Compiled
at [...]".

The 'cf_time' and 'cf_by' values show up in 'config.h' and
in 'Config_heavy.pl'.

Use the output of 'uname -s' instead of 'uname -a' to avoid recording
the kernel version ('uname -o' leads to directory names like
'x86_64-gnulinux' instead of 'x86_64-linux', which might cause breakage
down the road.)
