app_profile: Allow case-insensitive matching for cmdline

Add an "ignore_case" flag under profile.match.cmdline. If it's set, then
it will pass FNM_CASEFOLD to fnmatch (assuming that FNM_CASEFOLD is
supported).

This is mainly for Wine, which has to treat filenames as
case-insensitive.

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables VULKAN_CFLAGS
and VULKAN_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
