Compressed user-mode plugins aren't recognized

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create an user-mode plugin.
2. Compress it with psp-packer.
3. add it to vsh.txt.

What is the expected output?
Plugin runs.

What do you see instead?
Plugin doesn't load.

What version of the product are you using? On what operating system?
6.60 Pro

Please provide any additional information below.
Currently xmbctrl(1.3) and categories_lite (if compressed) doesn't load at if 
they are compressed with psp-packer on 6.60 Pro. These plugins works on 6.39 
Pro and neur0n's 6.60 ME fine so its only a 6.60 issue. When enabling the debug 
mode, this can be read in the log:

load_start_module: load module ms0:/seplugins/category_lite.prx -> 0x80020148

load_start_module: load module ms0:/seplugins/xmbcontrol/xmbctrl.prx -> 
0x80020148

That means SCE_KERNEL_ERROR_UNSUPPORTED_PRX_TYPE. This is incorrect as the 
plugin loads properly on 6.39 Pro or 6.60 ME.

Update: if a prx is compressed with 0x0800 attrib and newer psp-packer (the one 
by neur0n) then the plugin loads on 6.60 Pro but fails on 6.20.

After some debugging i found that the error comes from _sceKernelCheckExecFile 
in SystemControl/loadercore_patch.c, sctrlKernelCheckExecFile doesn't 
recognizes the prx as valid.

We'll need to take a look at.
