Fixes bugs in the drcacheoff.legacy and drcacheoff.snappy tests which do not account for different locales in matching numbers.
Tested: Dots instead of commas: $ LANG=de_DE.UTF-8 ctest -j4 -R drcacheoff 100% tests passed, 0 tests failed out of 36 No thousands separator at all: $ LANG= ctest -j4 -R drcacheoff 100% tests passed, 0 tests failed out of 36
