x86: beautify vmlinux_32.lds.S

Beautify vmlinux_32.lds.S:

 - Use tabs for indent
 - Located curly braces like in C code
 - Rearranged a few comments

To see actual differences use "git diff -b" which
ignore 'whitespace' changes.

The beautification is done to prepare a unification
of the _32 and _64 variants of the linker scripts.

[ Impact: cleanup ]
