MDEV-13785: move defination HAVE_LARGE_PAGES -> HAVE_LINUX_LARGE_PAGES

HAVE_LARGE_PAGES was always Linux but now there is
HAVE_SOLARIS_LARGE_PAGES in the code base. Innodb was using HAVE_LINUX_LARGE_PAGES
so keep this consistent everywhere.

Test plan:

$ grep Hugepagesize: /proc/meminfo
Hugepagesize:       2048 kB

$ sudo sysctl vm.nr_hugepages=1024
vm.nr_hugepages = 1024
$ sudo sysctl  kernel.shmmax=$(( 2 * 1024 *1024 * 1024 ))
kernel.shmmax = 2147483648

No errors in ouput:
