libhugetlbfs: Fix linking tests with lld

ld.hugetlbfs runs $LD as the real linker and adds the GNU ld only
-Ttext-segment option for --hugetlbfs-align links on arm/aarch64, i386 and
ppc64. Now that LD is ld.lld this fails with

  ld.lld: error: -Ttext-segment is not supported. Use --image-base if you intend to set the base address

Teach ld.hugetlbfs to use --image-base when the linker is LLD.

+Subject: [PATCH] ld.hugetlbfs: Use --image-base with LLD
+
+LLD does not implement the GNU ld -Ttext-segment option and errors out:
+
+  ld.lld: error: -Ttext-segment is not supported. Use --image-base if you intend to set the base address
+
+which breaks linking the --hugetlbfs-align testcases when LD is lld. Detect
+LLD and pass the equivalent --image-base instead. LLD reads the value with
+base auto-detection, so emit the address with a 0x prefix, which GNU ld also
+accepts.
