Subject: [PATCH] Fix a compilation error in TPMLIB_GetPlaintext

Fix a compilation error that newer gcc versions may complain about:

tpm_library.c: In function 'TPMLIB_GetPlaintext':
tpm_library.c:441:11: error: assignment discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]
  441 |     start = strstr(stream, starttag);
      |           ^
At top level:
cc1: note: unrecognized command-line option '-Wno-self-assign' may have been intended to silence earlier diagnostics
cc1: all warnings being treated as errors
