libtool: remove /absolute/path/to/host references

Removed all instances of -fdebug-prefix-map in LTCFLAGS
declaration because they contain references to host system
and are not needed.

/absolute/path/to/host/dd was replaced with 'dd' in
lt_truncate_bin declaration.

Please take note that the location of regex is important
for DEBUG_PREFIX_MAP. Removal of DEBUG_PREFIX_MAP has to be
done before other regex command modify its option value.

Both are modified because they affect binary reproducibility.

[YOCTO #11656]
