Fix incorrect typeset -L/-R/-Z on input with spaces (re: bdb99741)

Browse source 
The typeset output for -L/-R/-Z seems to be wrong when the input
has leading/trailing spaces. This started occurring after the
dynamic buffer size changes introduced in name.c as part of the
fix for <https://github.com/ksh93/ksh/issues/142>.

Test script:
  typeset -L8  s_date1=" 22/02/09 08:25:01"; echo "$s_date1"
  typeset -R10 s_date1="22/02/09 08:25:01 "; echo "$s_date1"
  typeset -Z10 s_date1="22/02/09 08:25:01 "; echo "$s_date1"

Actual output:
22/02/0
  08:25:01
0008:25:01

Expected output:
22/02/09
9 08:25:01
9 08:25:01

src/cmd/ksh93/sh/name.c: nv_newattr():
- Simplify allocation code, replacing the earlier dynamic buffer
  size calculation with just the greater of the strlen and size.
