restorecond: Musl compatibility for GLOB_BRACE and GLOB_TILDE

musl doesn't implement GLOB_BRACE and GLOB_TILDE, so simply don't use
them there. This affects restorecond -u but braces are not used in the
example configs. GLOB_TILDE is on the roadmap[1] for musl 1.1.21 so
restorecond -u should be fine soon.
