lib/pager: don't use pager if command not available

for example:
 # PAGER=foo dmesg -H
 sh: foo: command not found

the same problem is we have with fdisk 'l' command:

 # PAGER=foo fdisk /dev/sda
 Welcome to fdisk (util-linux 2.30-rc2-33-41b71).
 ...
 Command (m for help): l
 sh: foo: command not found

It seems better to don't use pager at all if not available.
