This patch fixes 2 issues related to symbolic links:
1. when "fs ls" a directory, symbolic links are not shown.
It is because Ext2fsLs() only shows regular files and directories.
2. when "fs ls <symbolic_link>" the output is incorrect.
It is because File->FileNamePtr points to a local variable,
"NameBuf" in Ext2fsOpen(), if the file is a symbolic link
This patch replaces File->FileNamePtr with FileNameBuf.
It slightly increases Ext2fsLs/Ext2fsOpen/SearchDirectory time,
because of the use of strcpy and strcat.
Test method:
1. create a regular file, "a", in directory "x"
2. create a symbolic link file, "b", pointing to "a".
3. under the shell of OSLoader,
"fs ls x"
- expected result: a, b (symbolic link)
"fs ls x/a"
- expected result: a and its file size is shown
"fs ls x/b"
- expected result: b -> a, and the file size of a is shown
