testsuite: xfail g++.dg/gcov/pr16855*.C on Solaris [PR52477,PR81337]

The g++.dg/gcov/pr16855*.C tests FAIL on Solaris:

FAIL: g++.dg/gcov/pr16855.C  -std=gnu++17  gcov: 1 failures in line counts, 0 in branch percentages, 0 in condition/decision, 0 in prime-paths, 0 in return percentages, 0 in intermediate format, 0 failed in filters
FAIL: g++.dg/gcov/pr16855.C  -std=gnu++17  line 24: is #####:should be 1
FAIL: g++.dg/gcov/pr16855.C  -std=gnu++26  gcov: 6 failures in line counts, 0 in branch percentages, 0 in condition/decision, 0 in prime-paths, 0 in return percentages, 0 in intermediate format, 0 failed in filters

FAIL: g++.dg/gcov/pr16855.C  -std=gnu++26  line 49: is 3:should be 1

Same for -std=gnu++98.

The issue has long been known and the failures generate an excessive
amount of noise.  Since the PRs haven't seen any activity in years, this
patch xfail's them.

Tested on i386-pc-solaris2.11, sparc-sun-solaris2.11,
x86_64-pc-linux-gnu, and x86_64-apple-darwin25.1.0.
