fluentbit: improve path munging in debug source files

Just remapping TMPDIR to TARGET_DBGSRC_DIR results in the files that
end up in the -src package containing lines such as

  #line 196 "/usr/src/debug/fluentbit/4.0.1//work/cortexa76-oe-linux/fluentbit/4.0.1/sources/fluentbit-4.0.1/lib/cmetrics/src/cmt_decode_prometheus.l"
  #line 1561 "/usr/src/debug/fluentbit/4.0.1//work/cortexa76-oe-linux/fluentbit/4.0.1/build/lib/cmetrics/cmt_decode_prometheus_parser.c"

By instead remapping both B and S, we strip more of the irrelevant
part of WORKDIR, and one ends up with line directives in the -src
package that actually match the source files' location in that
package:

  #line 196 "/usr/src/debug/fluentbit/4.0.1/lib/cmetrics/src/cmt_decode_prometheus.l"
  #line 1561 "/usr/src/debug/fluentbit/4.0.1/lib/cmetrics/cmt_decode_prometheus_parser.c"

  $ find packages-split/fluentbit-src/ -name cmt_decode_prometheus*.[cl] | sort
  packages-split/fluentbit-src/usr/src/debug/fluentbit/4.0.1/lib/cmetrics/cmt_decode_prometheus_lexer.c
  packages-split/fluentbit-src/usr/src/debug/fluentbit/4.0.1/lib/cmetrics/cmt_decode_prometheus_parser.c
  packages-split/fluentbit-src/usr/src/debug/fluentbit/4.0.1/lib/cmetrics/src/cmt_decode_prometheus.c
  packages-split/fluentbit-src/usr/src/debug/fluentbit/4.0.1/lib/cmetrics/src/cmt_decode_prometheus.l
  packages-split/fluentbit-src/usr/src/debug/fluentbit/4.0.1/lib/cmetrics/src/cmt_decode_prometheus_remote_write.c

and that also matches the remapping that the compiler is instructed to
do via the -ffile-prefix-map mechanism.
