script: use %n at the end of default tstamp_fmt

Since we are only outputting time-stamps when they differ
ending it with a newline, interferes with the output less.

script add -T fmt to print time-stamps

script -r is useful for recording time-stamps of when output
happened. With -T, rather than playback the script in real-time
we simply print the time-stamps to show when the output happened.

This is very useful for example, for analyzing boot time activity.

If the fmt provided contains no % characters the default
%n@ %s [%Y-%m-%d %T]
is used, which lends itself to analysis by tools as well as humans.

Have script accept and ignore -e for Linux compat

In the util-linux version of script, it will always exit with succes.
Except when run with -e, in which case it will have the exit value of
the child. BSD Script already uses the child's exit value for its exit
value. Some config and other helper scripts depend on being able to
specify -e. Accept it for compatibility since we'll already to the
right thing, but otherwise we ignore it.

When script(1) reads EOF from input it starts spinning on zero-byte
reads eating 100% CPU. Fix this by skipping select on STDIN after
reading EOF -- permanently if STDIN is not terminal and for one second
if it is.

Also after reading EOF from STDIN we have to pass it to the program
being scripted. The previous approach was to write zero bytes into the
pseudo-terminal. This does not work because zero-byte write does not
have any effect on read. Fix this by sending VEOF instead.
