Parsing of the build.log fails when a command has \"\ about codechecker

@igalex Doesn't seem fix to me.
With this line:

        "command": "gcc -I/usr/include/c++/5 -I/usr/include/x86_64-linux-gnu/c++/5 -I/usr/include/c++/5/backward -I/usr/local/include -I/usr/include/x86_64-linux-gnu -I/usr/include -E -MM -DU_ATTRIBUTE_DEPRECATED= -DU_COMMON_IMPLEMENTATION -DU_USING_ICU_NAMESPACE=0 -DU_NO_DEFAULT_INCLUDE_UTF_HEADERS=1 -DUCONFIG_NO_LEGACY_CONVERSION -DUCONFIG_NO_TRANSLITERATION -DUCONFIG_NO_REGULAR_EXPRESSIONS -DUCONFIG_NO_BREAK_ITERATION -DU_CHARSET_IS_UTF8 -I/home/sylvestre/dev/mozilla/ff/mozilla-inbound/intl/icu/source/common -I/home/sylvestre/dev/mozilla/ff/mozilla-inbound/intl/icu/source/i18n -ffunction-sections -fdata-sections -D_REENTRANT -DU_HAVE_ELF_H=1 -DU_HAVE_ATOMIC=1 -I/home/sylvestre/dev/mozilla/ff/mozilla-inbound/intl/icu/source/common -DDEFAULT_ICU_PLUGINS=\"/usr/local/lib/icu\"\  /home/sylvestre/dev/mozilla/ff/mozilla-inbound/intl/icu/source/common/icudataver.c",

I have the same problem when I load the compile_commands.json generated by espressif/idf:v4.4.1. And I suspect it's because of those escape backslashes (\)

ESP-IDF adds these \\\:
-DMBEDTLS_CONFIG_FILE=\\\"mbedtls/esp_config.h\\\"

Expanded section:
"command": "/opt/esp/tools/xtensa-esp32-elf/esp-2021r2-patch3-8.4.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc -DHAVE_CONFIG_H -DMBEDTLS_CONFIG_FILE=\\\"mbedtls/esp_config.h\\\" -DUNITY_INCLUDE_CONFIG_H -DWITH_POSIX -I/opt/esp/idf/comp>

I haven't tried it yet, but if single quotes solve the problem, with SED you could replace the \\\ by '
