build: correct minor typo in lttng help message

Currently the help message when using --with-lttng looks like this:

$ ./configure --help | grep 'with-lttng'
  --with-lttng          build with Lttng (Only available to Linux)

This commit makes the help message consistent with the error message
that is raised if --with-lttng is used on a non-Linux operating
system:

$ ./configure --help | grep 'with-lttng'
  --with-lttng          build with Lttng (Only available on Linux)
