libcamera: base: utils: Support C libraries lacking locale support
Not all C libraries include support for locale objects (locale_t) and the strto*_l() family of functions. A notable example is uClibc that can be compiled with a hardcoded "C" locale. Compilation then fails as the newlocale(), freelocale() and strtod_l() functions are not defined. Fix the compilation breakage by checking for the availability of the locale_t type, and fall back to strtod() when the type isn't available. This may not lead to the correct result if support for locale objects isn't available and the locale isn't hardcoded to "C", but that is such a corner case that we will likely never encounter it.
