[LTP] fcntl24,25,26 fail when run on tmpfs

[Matt Fleming <matt@console-pimps.org>]

[-- Attachment #1: Type: text/plain, Size: 238 bytes --]

Attached is a patch to skip testcases fcntl24, fcntl25 and fcntl26 if
the host is running on tmpfs. The reason being that, as documented here
http://bugzilla.kernel.org/show_bug.cgi?id=13626, F_SETLEASE and F_WRLCK
cannot work on tmpfs.
