- Improved portability of the sql-bench Perl scripts by replacing

   the calls of external programs "uname" and "pwd" with Perl builtin
   functions "cwd()" and "POSIX::uname()"


sql-bench/as3ap.sh:
   - portability fix: don't call external "pwd" command, use the "cwd()"
     builtin function instead.
sql-bench/bench-count-distinct.sh:
   - portability fix: don't call external "pwd" command, use the "cwd()"
     builtin function instead.
sql-bench/bench-init.pl.sh:
   - portability fix: don't call external "pwd" command, use the "cwd()"
     builtin function instead.
   - portability fix: don't call external "uname" in various combinations,
     use POSIX::uname() instead.
sql-bench/copy-db.sh:
   - portability fix: don't call external "pwd" command, use the "cwd()"
     builtin function instead.
sql-bench/crash-me.sh:
   - portability fix: don't call external "pwd" command, use the "cwd()"
     builtin function instead.
   - portability fix: don't call external "uname" in various combinations,
     use POSIX::uname() instead.
sql-bench/innotest1.sh:
   - portability fix: don't call external "pwd" command, use the "cwd()"
     builtin function instead.

   - portability fix: don't call external "pwd" command, use the "cwd()"
     builtin function instead.
sql-bench/innotest1b.sh:
   - portability fix: don't call external "pwd" command, use the "cwd()"
     builtin function instead.
sql-bench/innotest2.sh:
   - portability fix: don't call external "pwd" command, use the "cwd()"
     builtin function instead.
