Macros fix: wlib doesn't like double backslashes as a path entries separator

[valerius]

When compiling VBox (PC BIOS and VGA BIOS) for OS/2 host, a Watcom librarian is used. The error is the following:

  C       VBoxPcBios32 - {C}/src/VBox/Devices/PC/BIOS/pci32.c
  AR      VBoxPcBios32
Error! Cannot find file 'N:\\src\\vbox\\out\\os2.x86\\release\\obj\\VBoxPcBios32\\pci32.obj'

The cause is that the double '\' is used in .rsp and a command line for wlib.exe:

VBoxPcBios32.rsp:
+"N:\\src\\vbox\\out\\os2.x86\\release\\obj\\VBoxPcBios32\\pci32.obj"

kmk --version
kmk - kBuild version 0.1.9998 (r2687)

[n:\src\vbox\out\os2.x86\release\bin]rpm -q kbuild
kbuild-0.1.9998.6-1.i386

-- This is the last kBuild RPM OS/2 port

The fix is to change TOOL_OPENWATCOM_FIX_SLASHES to TOOL_OPENWATCOM_FIX_SLASHES_SQ (the patch is attached).

Note that the same problem exists in OPENWATCOM-16.kmk and also needs to be fixed, just in case.
