client/X11: Reintroduce handling for relieving filename restriction

Browse Source 
Commit 6492a00959 introduced a way to
relieve the filename restriction, which ensured that file lists
containing files with names, that have characters, which are not allowed
on MS Windows.
This relief handling kicked in, when xfreerdp did not connect to MS
Windows RDS.
Commit d521c7fa74 got rid of any
wClipboardDelegate occurrence in xf_cliprdr.c, which also got rid of the
filename restriction relieve handling.
However, the relief handling was not added back, so do it now.
