bitbake: siggen: Avoid taskhash mismatch errors for nostamp tasks when dependencies rehash

Browse Source 
An example:

NOTE: recipe binutils-cross-testsuite-2.32.0-r0: task do_check: Started
ERROR: Taskhash mismatch b074da4334aff8aa06572e7a8725c941fa6b08de4ce714a65a90c0c0b680abea versus 17375278daed609a7129769b74a1336a37bdef14b534ae85189ccc033a9f2db4 for /home/pokybuild/yocto-worker/qemux86-64/build/meta/recipes-devtools/binutils/binutils-cross-testsuite_2.32.bb:do_check
NOTE: recipe binutils-cross-testsuite-2.32.0-r0: task do_check: Succeeded

Is caused by a rehash in a dependency happening somewhere earlier in the build
and the taint being reset.

Change the code so that nostamp taints are preserved to avoid the issue.
