tpm2-abrmd: fix do_compile error

After commit [5ef547b autoconf-archive: update to 2019.01.06]
applied in oe-core, there comes below error
when build tpm2-abrmd:
| NOTE: make -j 48
| Makefile:4381: *** missing separator.  Stop.

So backport a patch from tpm2-abrmd upstream to fix
this failure.

+Subject: [PATCH] build: update for ax_code_coverage.m4 version 2019.01.06
+
+ @CODE_COVERAGE_RULES@ doesn't exist any more and needs to be replaced.
+ Also includes a compatibility wrapper for older versions of the file.
+
+There is a bug in the new version of ax_code_coverage.m4
+(cf. https://github.com/autoconf-archive/autoconf-archive/pull/182):
+AM_DISTCHECK_CONFIGURE_FLAGS is recursively defined, which causes
+"make distcheck" to fail in combination with --enable-code-coverage.
+This is fixed by overwriting the faulty definition.
+
+Upstream-Status: Backport [https://github.com/tpm2-software/tpm2-abrmd/commit/3cacba40114f26650c681b067ff0495f4a0dd186]
