bazel: bump gawk to 5.3.2.bcr.7 for hermetic-llvm compatibility

gawk's vendored gnulib headers deliberately shadow libc headers; under
toolchains that inject libc headers as leading -isystem entries
(hermetic-llvm, #10812) gawk@5.3.2.bcr.2 fails to compile (BCR #7642).
5.3.2.bcr.7 carries the upstream BCR fix (#7989). Behavior-neutral on
the current toolchain.
