[PATCH] kbuild: Remove unnecessary 'T' modifier in cmd_ar_builtin_fixup

[Nathan Chancellor]

In cmd_ar_builtin_fixup, the 'T' modifier was added to '$(AR) mPi' to
work around a bug in llvm-ar that caused thin archives to be silently
converted to full archives [1]. Since commit 20c098928356 ("kbuild: Bump
minimum version of LLVM for building the kernel to 15.0.0"), all
supported versions of llvm-ar have this issue fixed, so the 'T' modifier
and comment can be removed.
