[lldp] Merge wrapped lines.

Some devices return their description on multiple lines such as:

    lldp.eth0.chassis.descr=cisco CISCO7609-S running on
    Cisco IOS Software, c7600s72033_rp Software (c7600s72033_rp-IPSERVICESK9-M), Version 12.2(33)SRE3, RELEASE SOFTWARE (fc1)

The generated fact will result as:

    "descr": "cisco CISCO7609-S running on"

This patch fixes the line wrapping to return the full description
handling line breaks:

    "descr": "cisco CISCO7609-S running on\nCisco IOS Software, c7600s72033_rp Software (c7600s72033_rp-IPSERVICESK9-M), Version 12.2(33)SRE3, RELEASE SOFTWARE (fc1)\nTechnical Support: http://www.cisco.com/techsupport\nCopyright (c) 1986-2011 by Cisco Systems, Inc.\nCompiled Wed 26-Jan-11 06:54 by prod_rel_team"
