package/binutils: fix an OpenRISC binutils 2.37 patch

When binutils 2.37 was introduced in commit
62f02329 ("package/binutils: add
version 2.37"), the patch
0008-or1k-fix-pc-relative-relocation-against-dynamic-on-P.patch was
not properly updated. Indeed, between binutils 2.36 and 2.37, binutils
has switched to using the standard "bool" type, so instead of using
TRUE/FALSE, true/false must be used.

With this change, the binutils patch matches the one that was merged
upstream.
