valgrind: set ac_cv_path_PERL to /usr/bin/env perl

The shebang's max length is usually 128 as defined in
/usr/include/linux/binfmts.h:
  #define BINPRM_BUF_SIZE 128

So there would be errors when /path/to/hosttools/perl is longer than 128.

Set ac_cv_path_PERL to "/usr/bin/env perl" to fix the problem.

 # valgrind likes to control its own optimisation flags. It generally defaults
